Arsène Wenger hopes to have four players back for the visit of Liverpool this weekend.

Johan Djourou (shoulder) and Wojciech Szczesny (finger) were last seen departing major cup ties against Manchester United and Barcelona respectively and both face fitness tests ahead of Sunday's Premier League clash.

Alex Song (knee) and Denilson (toe) could return to bolster Arsenal's midfield but Bacary Sagna (knee) is a major doubt while goalkeeper Manuel Almunia (knee) is also doubtful.

"We have no [new injuries] but we have a big doubt on Sagna," Wenger told Arsenal TV Online on Thursday.

"Djourou and Wojciech are question marks. Will they be fit? That all has still to be decided. We have two more days to find out. It could be a possibility that they could be available.

"It's difficult to say [what their chances are]. We have a test today [Thursday], we have a big test to see how they survive the training session. That will be very important.

"Denilson and Song have a chance to be available as well."

Thomas Vermaelen will not be fit to face Liverpool but Wenger confirmed that the Belgian defender is back in full training after missing most of the season with tendon problems.

"I am not reluctant [to use him] but he is not match fit yet," said the manager. "He just joined the team this week so we have to be a bit patient with him."
