West Ham United's on-loan midfielder Joao Mario is unsure about whether he will remain at the club beyond the season's end.

Mario joined from Inter Milan on loan in the January transfer window. His impressive performances are one of the reasons why West Ham look set to avoid relegation.

However, Mario is unsure about where his future lies.

"I am not sure yet," he said in an interview with the Evening Standard.

"It depends on a lot of things and I have the World Cup with Portugal this summer.

"At the moment, I am just thinking about this game against Stoke and the rest of the season.

"Then I will decide."
