Swansea boss Michael Laudrup reckons Arsenal must take three points from the Liberty Stadium on Saturday to keep their hopes of a top-four place alive.
"Chelsea are at home this weekend, so if they win and Arsenal don't win here, they would be eight points behind and with only nine games to go that may be too big a gap," he said.
"So it is a very important game for them to keep alive the possibility of going into the Champions League next season."
But Laudrup gave his backing to counterpart Arsene Wenger, despite the club's eighth season without silverware.
"He (Wenger) has been there 17 years now," Laudrup added. "If the fans want trophies then eight years is of course a long time but what he has achieved there is great.
