Inter Milan midfielder Wesley Sneijder has rejected claims from Marco van Basten that he has lost his focus.

Former Holland international Van Basten had accused his compatriot on giving up on Inter's season already and turning his attention to Euro 2012.

"He's one of the best midfielders in the world; the problem is his mentality," the former AC Milan star told Sky Sport Italia. "He knows he cannot win the championship and is already thinking about the European Championship.

"When Mourinho was there, he was at his most motivated but now at Inter there is a bit more chaos and suffering.

"But it's not just the fault of Inter, it's also Sneijder, who should be more professional."

However, Sneijder has rubbished Van Basten's words, insisting that he is motivated for every match.

"I'm not thinking of Euro 2012 yet," Sneijder wrote on Twitter. "I live from game to game!!

"So I'm thinking [only] about tonight's game ... With concentration and as a professional. I'm ready ..."

Sneijder is expected to start for Inter against Marseille this evening.
