Former West Ham boss David Moyes has no doubts about the quality of Marko Arnautovic.

He worked with the Austrian last season.

Moyes said on Bein Sports: “There was a bit of changing to be done in the January transfer window.

“We had to try and get a few players out and change it around a little bit.

“But in the end if you look at what we did with someone like Marko Arnautovic.

“We changed him from a wide player and someone who a lot of people thought was maybe a bit sultry and didn't perform that well.

“We got him to a centre forward who was outstanding in that period.

“And in truth he could probably play for most of the top teams."
