Alexis Sanchez has insisted that there is “no problem” with him playing against Manchester United this weekend, despite suffering an injury while on international duty.

The Arsenal forward recovered from a ‘low-grade’ thigh problem to score two goals in Chile's 3-1 World Cup qualifying win over Uruguay on Tuesday.

Sanchez will be assessed by Arsenal’s medical team ahead of their trip to Old Trafford, but the 27-year-old fully expects to be passed fit.

“I travel today [Wednesday] to London,” Sanchez told journalists after Chile’s victory. “I will train on Friday and travel the same day to Manchester to play Saturday midday.

“There is no problem with me playing,” he added.

Arsène Wenger raised concerns about Sanchez’s fitness last week, fearing that Chile could exacerbate the injury by playing him against Uruguay.

Sanchez missed two months of Arsenal's 2015/16 campaign after aggravating a hamstring problem in a 1-1 draw at Norwich City last November.

Wenger shouldered the responsibility for risking Sanchez that day and made it clear that the forward's national team should not make the same mistake.

“We have to get access for our medical staff to the MRI scan to see what grade it is, how bad it is and make absolutely sure they don’t make any suicidal decision that could harm his future for two or three months,” he said.

Sanchez, while deployed as a central striker, has scored six goals in 11 Premier League appearances so far this season.
