Former Arsenal manager George Graham believes Arsene Wenger will achieve his 'best accomplishment' if the club can finish in the top four this season.
The Gunners have experienced an indifferent first half of the campaign and currently sit five points off fourth after 22 matches.
Graham, who led the club to two first division titles and a FA Cup in the late 1980s and early 1990s, feels the current Arsenal squad is not deep enough, compared to say that of North London rivals Tottenham, suggesting that Wenger has his work cut out for him to grab a Champions League spot come seasons end.
"And you look at Arsenal - they've got to have their best team out to get into the top four. But if they've not got their best team I think the squad members who are coming in are just not quite good enough. There's plenty of revenue that should be coming into the club I can't understand why they're not getting a better class of player.
"Dennis Bergkamp, Robert Pires, Patrick Vieira, Thierry Henry, Marc Overmars, Freddie Ljungberg - if you don't replace those players with a similar ability, you are slowly going to slide away down the league.
"I hope that doesn't happen because Arsene's been fantastic for Arsenal and English football and I would hate to see that just slip away. If they can get into the top four this season, that'll be one of his best accomplishments at the club.""You see somebody like Spurs and they've got so many players for all the positions," said Graham.
