Arsenal "have to be careful" if they are going to consider a move for Liverpool's Adam Lallana this summer, says Nigel Winterburn, who has raised concerns over the playmaker's injury record.
"Lallana is a player I like but he has had so many injuries problems," the ex-Arsenal defender told Metro Sport.
"When you’re looking to bring players in for the first team or even the squad, you have to be careful."
It has been reported that Arsenal could end up losing Mesut Ozil, Alexandre Lacazette and Pierre-Emerick Aubameyang at the end of the season, with all three men being touted for moves away from Emirates Stadium.
A switch to MLS has been mooted for Ozil, while Barcelona have been linked with Lacazette and Aubameyang consistently over the past few months.
Winterburn went on to insist that Arteta may be unable to prevent any key players from departing, before once again stressing the need for the club to be thorough in their pursuit of new additions.
"You want to keep all the best players you got, you want to work with them and play with them," he said.
"Unfortunately, players are earning massive amounts of money now and if they want to force a move they will.
"I’m more interested in the players that come to the club. Whether they’re highly rated or not, we’re only interested in what they do when they get here.
"If you’ve got a World Cup winner with all the stats and everyone is raving on about him, and then he comes to Arsenal and doesn’t do very well, we’d all be saying what a waste of time and money that was."
