England manager Fabio Capello believes Arsenal need to add some fresh blood to their squad but concedes Arsene Wenger faces a tough task to bring in quality additions before the transfer window closes.
Wenger has come under pressure from Gunners fans following a difficult start to the season, which has seen Arsenal pick up one point from their opening two Barclays Premier League fixtures, their squad badly hit by injuries and suspension, and the loss of captain Cesc Fabregas to Barcelona, while Samir Nasri's future remains unresolved.
Asked if he thought Wenger should continue at Arsenal, Capello said on Sky Sports' Goals on Sunday programme: "I hope he will stay on, I have a good relationship with him, he's a really good manager, but it's not a good moment, it's difficult after six years without a trophy for such an important club like Arsenal."
Capello added: "I think he needs to buy some new players, some important players, but it's difficult to find top players at this moment, because the best players are playing with important teams, teams who want to win.
"I think Arsenal have got money but it's difficult to find top players to improve the team. Because if you spend the money buying normal players, it's not good, you need to spend money to improve the team."
Speaking on the same programme, the FA's director of football development Sir Trevor Brooking also believes Wenger is in a tough position, especially with regards to Nasri, who is out of contract next summer.
Brooking, who felt Nasri was ""fantastic" during the first half of last season, said: "At the start of the summer if you'd have said Fabregas or Nasri I'd say keep Nasri, although that's easy for me to say.
"If he's only got one year to go and you're going to let him go for nothing next summer, and if you can get £20million for him now, that's a decision but then you've got to try and bring in the same quality of player.
"That's the thing that Fabio was saying and Arsene has said, 'I've got money but don't want to spend it on an average player that's not going to improve the squad', because then he will be criticised for buying in when he hasn't improved the team."
