Chelsea manager Jose Mourinho believes big-spending Arsenal are ready to challenge for the Premier League crown this season.
Arsenal finished 13 points behind Chelsea last season as the Blues won the Premier League at a canter, but Mourinho believes the arrival in recent years of the likes of Mesut Ozil, Alexis Sanchez, Calum Chambers and Mathieu Debuchy for more than £100million means the Gunners are ready to challenge for league honours.
Mourinho and Wenger have endured a fractuous relationship with the Blues boss calling the Frenchman a 'specialist in failure' and a 'voyeur' while the Gunners boss has accused the Special One of lacking respect and pushed his opponent at Stamford Bridge last season.

"If you add up the amounts clubs have spent in the last three or four years I think maybe you will find a surprise," Mourinho, who allowed goalkeeper Petr Cech to join Arsenal in an £11million deal last month.
“Get a calculator. That is one of the easiest things to do. It leaves no space for speculation. If you want to be honest, objective and pragmatic it is the easiest job for a manager or a journalist to do.
"If you put Ozil plus Alexis Sanchez, plus Chambers, plus Debuchy, you will find a surprise.
"It's a fantastic squad with good players, fantastic goalkeeper, they are more than ready to be a title contenders."
