Chelsea boss Andre Villas-Boas has hinted at a return for striker Fernando Torres in the Champions League this week.
The Spanish international is banned for three Barclays Premier League matches after seeing red against Swansea City, and watched from the stands as the Blues comfortably swept aside Everton at Stamford Bridge on Saturday.
Whilst the three-match ban applies domestically, it does not stop Torres playing in the Champions League, and the former Porto boss looks likely to turn to the £50 million January signing.
"Fernando is keeping fit in training and he also will be almost a month without playing for us in the Premier League, so I will decide in the next couple of days whether to use him on Wednesday," he said in a press conference earlier today (Monday).
"We cannot allow ourselves to relax against Genk but that is what can happen in a game which everyone expects you to win.
"Our group is still very open so we have to concentrate on taking six points from our next two games against Genk to put us in a good position to qualify for the next round.
"We were 10 minutes away from winning our last game away to Valencia and we let them equalise and now anything can happen in this group."
Chelsea made a winning start to their Group E campaign, beating Bayer Leverkusen at home before picking up a point at the Mestalla Stadium in Spain.
Wednesday night's Belgian visitors sit bottom of the group, but a point against Valencia in the first round of matches suggests they could cause problems in west London.
