Chelsea manager Jose Mourinho blamed a "dangerous" pitch as he has confirmed John Terry is a doubt for Sunday's clash at Tottenham after being stretchered off during his side's 4-0 Champions League win at Maccabi Tel-Aviv on Tuesday.
The Premier League champions kept their hopes of reaching the knockout phase in Europe alive with a convincing win in Israel, with Gary Cahill scoring in the first half before former Chelsea defender Tal Ben Haim was shown a straight red card for hacking Diego Costa.
Chelsea captain Terry was replaced for Kurt Zouma 19 minutes from time before Willian, Oscar and Zouma scored late on, and Mourinho -- who criticised the quality of the Sammy Ofer Stadium pitch in Haifa -- says the 34-year-old centre-back could now miss the important trip to White Hart Lane on Sunday.
"The surface was bad and dangerous," Mourinho said. "John has an ankle problem that we don't know yet the dimension of.
"For John to leave the pitch with the result 1-0 I know already that he is in trouble.
"My medical department is really good. John is a special guy, with a special desire to recover. But I think to leave the pitch with the result 1-0, I don't believe too much that he can play [against Spurs]."
Ramires was not in the matchday squad after suffering an injury in training on Monday, when Chelsea tried to minimise their time on the pitch.
"Yesterday we tried to protect [the pitch], we trained just a little bit. But by my surprise Maccabi were training after us, plus the warm-up before the game," Mourinho said. "The pitch was really bad. Ramires slid and had a muscular injury."
After Gary Cahill's opening goal, Mourinho took it upon himself to replace divots on the pitch in front of his technical area, and he said: "I think after what I did, I think it was worse. I tried."
The win keeps Chelsea on course to qualify from Group G with the Blues needing just a point to qualify, and the coach acknowledged the importance of his side's win after Dynamo shocked Porto with a 2-0 win in Portugal.
"It was very important especially with what happened in Porto," Mourinho said. "It is also important to have two victories in a few days. I hope tranquillity comes, morale comes, confidence comes.
"In this moment we are in a good position. [Maccabi] don't deserve such a hard punishment -- they did OK for periods of the game with 10 men."
Mourinho was happy with the first-half display, but felt the scoreline flattered his side.
"In the first half I could feel only the bad pitch stopped us from playing even better when we reached the last third," he said. "I think we played better matches today, but we lost.
"In the second half in the first 15, 20 minutes, I think we slept. We were too confident, we were waiting for the second goal to come.
"Only when we felt that we were in danger we had again a good reaction."
Asmir Begovic made a number of important saves with Chelsea a goal up until the latter stages, and Mourinho praised the goalkeeper -- standing in for injured No. 1 Thibaut Courtois -- for "a beautiful hand to keep a clean sheet."
Maccabi Tel Aviv boss Slavisa Jokanovic said his side were better than in the return contest in London, when Chelsea also won 1-0, but having Ben Haim sent off was challenging.
"It's very complicated 11 against 11 against Chelsea," Jokanovic said. "Many minutes with one player less is complicated for us. It can be a more important decision in the game.
"I believe we improved. At the end they scored three goals from set pieces."
