Arsenal midfielder Tomas Rosicky has claimed that any new signing would be a big help to the club for next season.
The Gunners have been linked with a number of players in recent months, including Manchester United striker Wayne Rooney and Swansea City's Michu.
"We are a club which loses one or two important players each summer, so we have to replace someone each time and that's always difficult," Rosicky told Idnez.cz.
"It seems as if nobody is leaving and, on the other hand, that some players could join Arsenal. It would help us a lot."
Arsenal finished the last campaign in fourth place in the Premier League table.
