Which is the more boring? Lack of success or sterile style of football.

Arsenal manager Arsene Wenger has accused Jose Mourinho of a lack of respect after the Chelsea manager said 10 years without winning the title must be “very boring”.

Some Arsenal fans chanted “boring, boring Chelsea” during last weekend’s goalless draw at the Emirates Stadium, a result which took the west London club a step closer to winning the league title for the first time since 2010.

In his post-match press conference, Chelsea manager Mourinho responded to the taunts by saying: “You support the club and you’re waiting, waiting, waiting for so many years without a Premier League title, so that’s very boring.”

Asked what he thought of Mourinho’s post-match statements, Wenger replied: “The biggest thing for a manager is to respect other managers. Some people have to improve on that.”

Asked if Mourinho should conduct himself with more dignity, the Arsenal manager answered: “Look, everybody lives with his own internal problems and I live with mine. That’s enough.”

This is not the first time the pair have clashed but Wenger believes that managers have a duty to not let their personal opinions influence their professional judgement.

He added: “You can have incidents with other managers sometimes. It gets a bit heated when you fight directly with them, but in the end I believe time heals and the important thing is to respect each other as much as you can.”
