Arsene Wenger has no plans to sell any of his Arsenal squad at the moment but has not ruled out departures before the end of the month.
Johan Djourou and Marouane Chamakh have both left on loan until the end of the season, while Sebastien Squillaci and Andrey Arshavin have been linked with moves away.
However, Wenger will not allow the pair to leave unless he brings in some new players first.
"At the moment no, (no one is leaving). We have a good squad, a balanced one. At the moment nobody can go out, unless we buy somebody," Wenger told Arsenal Player.
"At the moment our focus is to keep everybody. In every position we have two players. Three is too many and one is not enough."
Wenger had considered dipping into the transfer market in a bid to cope with a congested fixture list but Aaron Ramsey believes Arsenal's squad is strong enough to cope with six important matches before the end of January.
"It is a big month for us. We play some teams who are above us (in the Premier League) and we have an FA Cup game as well, so it is important to take these opportunities," Ramsey explained.
"We have Manchester City at home and Chelsea away, games that we did well in last season, so hopefully we can do the same again this year and that will set us up nicely for the run in to the end of the season."
