Petr Cech has claimed Chelsea are now Manchester United's main Barclays Premier League title rivals because Arsenal have blown too many chances to catch them.
Cech helped the champions beat Birmingham 3-1 at Stamford Bridge, while the Gunners squandered yet another two-goal lead to draw the north London derby 3-3 at White Hart Lane.
Those results saw Chelsea edge above Arsenal into second place on goal difference and close to within six points of United.
Blues goalkeeper Cech understandably questioned whether Wenger's men have what is takes to pounce on any United's slip-ups.
"Arsenal had a big game against Tottenham," he said. "They were 3-1 up and threw it away. Now they are third for the first time in a long time so let's see how they cope with this new situation.
"They had plenty of chances this season to close the gap and haven't taken them yet."
