Arsenal boss Unai Emery will have to wait until the summer before further strengthening his squad, according to a report.
The Spaniard is keen to bring in more players this month to add to the five signings made upon his arrival in the summer.
The Sun suggests that Arsenal risk missing out on a number of players, however, as Emery will not be allowed to bring in any new faces this month.
A cash injection from their sponsors later this year will go towards Emery's summer transfer kitty, though, and plans are said to already be in place for the end of the season.
Arsenal are fifth in the Premier League, three points adrift of the top four.
