Arsène Wenger says Jose Mourinho's return to Chelsea came as no surprise to him.
Mourinho, who led the Blues to five major trophies in his first spell at the club, returned to west London in the summer after managing Inter Milan and Real Madrid.
Sometimes we go overboard and that is part of the job. With the distance after, it always settlesArsène Wenger
And Wenger is looking forward to renewing his rivalry with the Portuguese coach when their teams meet in the Capital One Cup on Tuesday.
"It was not a big surprise [that Mourinho returned] because there was talk about it many times," Wenger told Arsenal Player. "When he left Madrid, it looked to be one of his best opportunities to come back.
"What the Premier League wants first is the quality of the games and his teams give you always a tough game. That is what you want."
During Mourinho's first spell at Stamford Bridge there were reports of disagreements between the Chelsea manager and Wenger, but the Frenchman insists there is no ill feeling.
"With all competitors there are ups and downs," said Wenger. "You could see that again yesterday between [Manuel] Pellegrini and Mourinho, because we put our whole heart into every single game.
"Sometimes we go overboard and that is part of the job. With the distance after, it always settles."Copyright 2013 The Arsenal Football Club plc. Permission to use quotations from this article is granted subject to appropriate credit being given to www.arsenal.com as the source 28 Oct 2013
