Mesut Ozil has urged Arsene Wenger to splash the cash in the summer transfer window to reinvigorate Arsenal after another disappointing season.

With Arsenal trailing league leaders Leicester by 11 points, albeit with a game in hand, and having slipped out of the Champions League and FA Cup the chances of a trophy at the Emirates this season are increasingly slim.

As Tottenham duke it out with Leicester for the right to claim a surprise league championship discontent is growing among Arsenal supporters who are increasingly frustrated at their side’s failure to take advantage of the struggles of Chelsea and the Manchester sides.

Critics suggest Wenger’s parsimonious nature, which saw him buy only Petr Cech last summer before bringing in bargain addition Mohamed Elneny in January, has cost Arsenal dearly in what may have been their best chance to claim a first league title since 2004.

Chelsea, Manchester United and City are all expected to spend big under new managers and Ozil urged Wenger to match that investment if Arsenal want to remain among the title favourites next season.

"We know that it will not be easy and that we need reinforcements if we want next season to be on top here again," he told Welt am Sonntag.

"It is again interesting to see who invests in who and how much the clubs do during the summer break.

"In addition, great coaches are coming into the league. I am thinking primarily of Pep Guardiola. Wherever he has been, he had success. He is a coach, keen on playing and his teams are feared.

"I wonder what he will do with Man City. He will be imprinting his football in England and people will be surprised."

Despite the sizeable gap that has opened up between Leicester and Arsenal Ozil, who deserves no blame for his side’s current predicament after enjoying his best season in English football, has refused to abandon hope of an unlikely title victory.

"I do not think it impossible," he told German newspaper Welt am Sonntag when asked about hunting down Leicester and winning the league.

"Although there are only a few games left, Leicester have a run against some of the big teams to come.

"We ourselves must in any case not allow any more slip-ups. The hope of the title is still there - we have the players for the title."
