Arsenal manager Arsene Wenger believes Chelsea have the Premier League title in the bag.
The Gunners were held to a 0-0 draw by the Blues at the Emirates Stadium on Sunday which suggests to Wenger that Jose Mourinho's team will have to have an almighty slip-up in order to lose their 10-point advantage on the rest of the league.
"We know Chelsea will be champions," he told Sky Sports. "A win for us today was absolutely necessary, so it's impossible for Chelsea to lose it now.
"Chelsea are a good side because they defend very well. In the recent games they haven't conceded and today they defended very well."
Wenger added: "(Chelsea) are not champions yet, but they will be."
