'Chelsea humiliation was players' fault', says Cech Petr Cech has blamed a collective failure by Chelsea's players for the club becoming the first holders of the Champions League to exit the competition at the group stage. His side's six-one victory against Nordsjaelland was rendered meaningless as Juventus won at Shakhtar Donetsk through an Oleksandr Kucher goal to leave Rafa Benitez's side third in Group E with 10 points, level with the Ukrainians but with an inferior record in the head-to-head games the teams played. Robert di Matteo, who led Chelsea to glory in May in Germany, was dismissed in November, largely as a result of the failure to launch an adequate defence of the trophy, but goalkeeper Cech insisted the blame was with him and his team-mates. "Unfortunately if you change your manager, you only change the manager, but the responsibility is on everyone," he said. We are all on the same boat, the manager and the players - the responsibility is the same for everyone. You are a team. We had results where we didn't win and we lost away to Donetsk and to Juventus, but I think the main difference was the draw at home to Juventus where we had gone two-nil up but we finished the game two-two. This is where the difference would have been. Unfortunately if you drop too many points in the group it is very difficult. We are out. We knew what could happen prior to the game that. The damage had been done before. We did what we could. We had a good performance and goals. We could only hope and, unfortunately, the other result did not go our way so we we are out. Now we need to focus on other competitions. In complete contrast, Celtic scored a dramatic 82nd minute penalty through Kris Commons to beat Spartak Moscow 2-1 and go through to the last 16 in the Champions League for the first time in five years as group rivals Benfica failed to beat Barcelona, for whom substitute Lionel Messi was carried off. Manchester United, who were already through, were beaten 1-0 at home by minnows Cluj.
