Ronny Deila says his inability to improve Celtic during his time at the club has killed him inside.The Norwegian, who took over from Neil Lennon in the summer of 2014, announced he was leaving in the summer just three days after the Scottish Cup semi-final defeat to Rangers.Deila led the club to the Scottish Premiership and League Cup double in his first year and the Hoops currently boast an eight-point lead over Aberdeen with five games remaining. Speaking ahead of the first post-split fixture against Ross County on Sunday, the former Stromsgodset manager said: It has been a tough week, there has been a lot of thinking and it hasnt started this week either.I have been thinking about this for a while because I havent felt the team has got the results they should have and, maybe more importantly, the performance and improvement I wanted.When I came in to the job, I talked about improving the team and playing attractive football and I think the last six months we havent had the improvement that we need. Ronny Deila says a lack of improvement at Celtic in the last six months was key to his decision to leave the club And with the speculation on his future with the club now over, Deila admits he is looking forward to bowing out with a second successive league championship.Improvement is one of my biggest values and when you dont get it, it kills me inside and I lose energy with that.I dont think there has been a lot of improvement and when you dont get improvement, the outside pressure is going to get harder and harder as well. Celtic have not improved in the manner Deila had hoped I have no problem dealing with that, I have been sitting in this room a lot of times and there has been a lot of difficult questions.That is not the problem, the problem is when you dont get improvements and the things you said you wanted to create when you came in the door, you havent created.One of the reasons we havent had that improvement is because of the pressure and speculation around me all the time. Celtic won the title in Deilas first season in charge That is why I think it is best for the club that new energy is coming into the club next season and now we can really focus on winning the five games and getting five-in-a-row. It is going to be a huge thing for me, the players and the whole club, this is why the decision has been made.And Deila has rubbished suggestions he was not in charge of the clubs transfer policy during his near two-year spell at the helm, insisting he takes full responsibility for the current strength of the squad.One, I signed the players so dont think about that. There is not one player here that I havent said yes to. Two, I knew what I went into when I took the job, said Deila, who brought 22 players to the club during his 22 months in charge. Erik Sviatchenko, one of Deilas last signings for Celtic This club want to be drifted in a positive way and have a positive economy and you have to drift in those circumstances.Everything that is coming into the club is going out of this club. That was said before I came here and its the same now. It is the philosophy of the club and I think its a very, very good thing. I have had good communications with the club and Peter [Lawwell]. I am not a bitter man. I was given a chance but I felt that lately we havent had the development that we wanted in the team.Also See:Evans: Leeds before CelticMoyes: No rush on Celtic jobKeane the ideal replacementLennon keen to speak with CelticYeezy 350 v2 France .J. -- New York Giants wide receiver Victor Cruz will miss the rest of the season after having surgery on his left knee.

Collaros also started Torontos 23-20 regular-season finale loss to Montreal — Ray didnt dress because the Argos had already clinched first in the East Division — but was one of three quarterbacks to play that day.

"I dont see anything that we need to add. We just have to get better," Carroll said.CINCINNATI -- A.J. Greens right foot caught the turf as he was tackled on Cincinnatis first pass attempt. He rolled over onto his back and immediately grabbed his right hamstring.And he stayed down.In that moment, the Bengals knew the game -- and their season -- had taken a turn.Green suffered a significant injury to his right hamstring on Sunday and was taken off the field on a cart. Cincinnati couldnt do anything consistently without its big-play receiver during a 16-12 loss to the Buffalo Bills.Sure, Andy Daltons two interceptions played a role. And Mike Nugents two missed extra points left the Bengals (3-6-1) needing a touchdown instead of merely a field goal at the end.But nothing hurt more than the loss of Green, who was third in the league in catches and second in yards receiving.Definitely, missing A.J. was a big piece, and it hurt us a lot, running back Jeremy Hill said.Without Green to challenge deep, a Bills defense known for giving up big plays was able to clamp down.Daltons longest completion was 21 yards to Tyler Eifert. The Bills had given up seven passes of 50 yards or longer, and their secondary was under criticism for its poor play overall.When Green got hurt, the Bills were able to play their comfortable coverages.We had some things for him, cornerback Ronald Darby said. It changed things a lot when he went out.Coach Marvin Lewis had no information about the severity of Greens injury. The durable receiver didnt bend his legg as he was helped to the sideline and taken to a cart, an indication it was serious.dddddddddddd The Bengals will have to figure on playing without him for the foreseeable future.You never want to lose a guy like that, Dalton said . Hes the best receiver in the league, so when you lose him it hurts.Some familiar problems returned as well. The Bengals couldnt get their running game going -- a problem all season long. Jeremy Hill had 62 yards, and the Bengals averaged only 3.4 yards per carry while getting 93 overall. Dalton had 10 of the yards.Cincinnati had the ball six times in the second half and managed only five first downs. They went three-and-out on four straight possessions.All season, its been mistake after mistake, Hill said.When they scored touchdowns in the first half, Nugent hit the upright on his two extra-point attempts, his kicks thrown off as he compensated for the wind. Nugent also missed an extra point and a field goal during a 27-27 tie with Washington on Oct. 30 in London.It just drives me crazy to have a poor performance that contributes to a loss, Nugent said. Thats the second time thats happened this year, that Ive contributed enormously to a loss. If I did what I was brought here to do, wed have two less losses, in my opinion.---AP NFL website: www.pro32.ap.org and http://twitter.com/AP-NFL ' ' '
