Alexis Sanchez has declared himself fit for Arsenal's clash against Manchester United dispelling any doubts about his fitness despite suffering a minor hamstring injury while on international duty with Chile.

The 27-year-old forward missed his country's World Cup qualifier against Colombia with a minor issue, but returned for their clash against Uruguay on Tuesday (15 November). Despite playing with a heavily strapped thigh, he didn't show any signs of the injury as he scored two goals to hand Chile a much needed 3-1 win and was substituted with six minutes left on the clock.

Arsene Wenger had warned against playing the former Barcelona star fearing that the minor injury could get worse and keep him out for months rather than weeks. However, Sanchez has allayed any fears and believes he will be ready to take the field at Old Trafford on Saturday (19 November).

"I travel today [Wednesday] to London. I will train on Friday and travel the same day to Manchester to play Saturday midday," the Arsenal star said after Chile's win on Tuesday, as quoted by the London Evening Standard.

"There is no problem with me playing," Sanchez added referring to the clash against the Red Devils.

The Chilean has been labelled one of the best in the world by his national team boss Juan Antonio Pizzi after he inspired his country to victory over Uruguay. The win helped them move into the automatic qualification places for the 2018 World Cup, and with three games to go in the qualifying, their prospect of making it to Russia in 2018 are looking positive.

"Individuals speak for themselves. Alexis is among the best players in the world. [But] I am more in favour of emphasising the strengths of the group. And it is what allowed us to turn the game," Pizzi said after the game, as quoted by ESPN FC.
