Liverpool hero Jamie Carragher says Nuno Tavares is to blame for Arsenal's top four failure last season.
Tavares signed on-loan for Olympique Marseille on the weekend.
Carragher believes the Portuguese defender is at fault for Arsenal's failure. Speaking to Sky Sports, he said: "Nuno Tavares has gone out on loan, I saw. I think if they had a better left-back, then you probably would be in the top four now.
"I don't like singling one player out, but I just think he cost you in certain games.
"I remember that game at Crystal Palace last season, it was on Monday Night Football and I said on TV: 'He has to come off at half-time'. I think he [Mikel Arteta] put Granit Xhaka at left-back in the end."
