Chelsea will find out who they will face in the Champions League semi-finals during Friday's draw in Switzerland.
Chelsea manager Jose Mourinho has been charged with misconduct by the Football Association for comments made following the Premier League game against Sunderland on Saturday.
Mourinho's 77-match unbeaten home record came to an end after Sunderland's 2-1 win.
He subsequently refused to answer questions, instead "congratulating" the game's referee Mike Dean and referees' chief Mike Riley.
Assistant coach Rui Faria has also been charged with two counts of misconduct.
Brazilian midfielder Ramires has been charged with violent conduct following an incident involving Sunderland's Sebastian Larsson.
Mesut Ozil will be even better during his second season in the Premier League, Arsenal team mate Per Mertesacker has said.
Ozil, who arrived from Real Madrid for £42 million last summer, has faced criticism after failing to sustain his early-season impact.
"He has adapted well but there is more to come from him, and I think the second season will be much better from him, because he's a fantastic player," Mertesacker told Arsenal's official website of his Germany colleague.
"He has shown some great skills but he needs to be more consistent, and that's what makes the difference at the end.
"With a pre-season ahead of him, there's more to come from him."
Chelsea manager Jose Mourinho has suggested that he could field a weakened team against Liverpool on Sunday as he prioritises the Champions League semi-final second leg against Atletico Madrid.
The Blues are five points behind Liverpool with just three games to go after Saturday's damaging 2-1 home defeat against Sunderland, leaving the Champions League as their biggest chance of silverware this season.
"I can't decide by myself, that's a decision where I have to listen to the club. I'm just a piece, the manager and no more than that," Mourinho said after the 0-0 draw in Madrid.
"We represent English football, we are the only English team in Europe. Spain has four teams and gives them all the conditions to have success.
"I know what I would do but I have to speak with the club. I would play with the players that are not going to play Wednesday."
Chelsea's first-leg draw with Atletico Madrid was marred by injuries to goalkeeper Petr Cech and captain John Terry.
Cech was ruled out for the season with a dislocated shoulder and Terry suffered an ankle injury to rule him out of next Wednesday's second leg at Stamford Bridge.
Jose Mourinho's selection problems are mounting after Frank Lampard and John Obi Mikel were ruled out of the second leg through suspension while Samuel Eto'o and Eden Hazard also struggling with injuries.
"Petr Cech's season over. And John - we have to play the final for him to play with us," Mourinho said.
"We had problems before the game, we had problems during the game, we lost four players during the game, two with injuries, two with yellow cards, but we will fight."
Chelsea have drawn 0-0 against Atletico Madrid at the Vicente Calderon in the first leg of their Champions League semi-final tie. Chelsea goalkeeper Petr Cech had to be taken off after an awkward fall 17 minutes into the game. Madrid will head to Stamford Bridge for next weeks second leg.
Chelsea defender David Luiz has said he is "still thirsty" for Champions League glory ahead of Chelsea's semi-final against Atletico Madrid on Tuesday night.
The Brazilian defender was part of the Chelsea side who lifted the famous trophy in 2012, and he is keen to repeat the feat in the final next month.
"We are all enthusiastic, playing in a semi-final is important for all. Atletico have great history and have won many titles. It's a dream to play in a semi-final, I was lucky enough to play [in the final] two years ago and I'm still thirsty for it," Luiz said.
"Everybody has a dream, tomorrow will be a great game and I'm privileged to play in such big matches.
"I think we have a great team, we've managed to reach the semi-final, we all want to win and let's hope we can get to the final."
Jose Mourinho insisted his only focus was Chelsea's Champions League semi-final against Atletico Madrid as he refused to discuss the London side's domestic difficulties.
The Blues face Atletico in the first leg of the European tie on Tuesday night as they aim to put a damaging loss to Sunderland behind them.
"If you want to speak about the Premier League you have 19 teams in England that you can speak with," Mourinho said.
"We are lucky to be involved in the Champions League, so we are lucky that in the next two days we don't think about the Premier League and what's happened and what is going to happen because now we only think about (the match)."
Mourinho has never led Chelsea into the Champions League final after previously losing against Liverpool in two semi-finals during his previous stint as manager.
