Arsenal will not win the Premier League again until Arsene Wenger replaces goalkeeper Manuel Almunia, according to former boss George Graham.
The Spaniard was at fault for West Brom's second goal in the Gunners' 3-2 home defeat on Saturday, letting Gonzalo Jara's shot slip through his hands and into the net.
"I think if you're going to really be realistic challengers for the Premiership you need a top top class goalkeeper," Graham told Five Live's Sportsweek programme.
"I think Almunia is a good goalkeeper, but there's about half a dozen good goalkeepers in the Premier League. I think Arsenal need an outstanding goalkeeper.
"I think they should be looking all round the world, not just in England or Europe."
