Arsenal defender Per Mertesacker has refused to give up on the Premier League title despite Leicester City restoring an 11-point gap over the Gunners at the weekend.
Arsene Wenger's side cruised to a 4-0 victory over Watford to close the deficit down to eight points, but the Foxes responded with a 1-0 win over Southampton on Sunday to edge closer to the title.
Arsenal do have a game in hand over both Leicester and second-placed Tottenham Hotspur, however, and Mertesacker believes that wins in their next four games will put them right in the mix.
"It's not totally over yet. If we win all of our matches, then we've got a good chance. We've got to keep focusing on that and that's why we're taking things game by game," he told German website sport1.de.
"We're trying to concentrate fully on our next game against West Ham. We have a bit more time now that we're not in any other competition so we don't have to concentrate on anything else, other than the title."
Arsenal have just two top-half teams left to face in their final seven games of the season.
