Chelsea F.C. host Manchester City on Saturday.
Branislav Ivanovic's goal in Chelsea's 1-0 vs Liverpool in the match gave Jose Mourinho's side a 2-1 aggregate win.
Speaking the morning after the game, Paul Lambert once again refused to divulge the content of his post-match discussion with the referee but said that Chelsea would not have been denied a penalty had they made an appeal in similar circumstances.
Victory in an occasionally ill-tempered game will give Chelsea boss Jose Mourinho enhanced belief that his side are ready for the battle sure to await them at Manchester United on Monday.
Ivanovic said he had forgiven Suarez for biting him during Chelsea's game against Liverpool in April, an infamous misstep which earned the controversial Uruguayan a 10-match ban.
The Liverpool forward, who has been fiercely criticised by the English media for his on-field antics, has been linked with Real Madrid.
The controversial Uruguayan finished the campaign as the club's top scorer with 23 league goals.
Chelsea will now hold both European club trophies until May 25, when Bayern Munich and Borussia Dortmund play this season's Champion's League final in London.
Uruguay striker Suarez, 26, was suspended on Wednesday after he was shown to have bitten Chelsea's Branislav Ivanovic on the arm last weekend.
