Belgium manager Roberto Martinez insists a knock Chelsea star Eden Hazard has picked up while on international duty is "nothing serious".

Hazard, 26, played 85 minutes in Saturday's (11 November) friendly against Mexico before he was replaced by his brother Thorgan having opened the scoring for his side in a 3-3 thriller. The Chelsea forward left the pitch carrying a slight knock which forced him to sit out of team training on Sunday, instead working away from the group ahead of Tuesday's match against Japan in Brugge.

Martinez however has moved to ease any concerns over the Blues star, however, telling a press conference on Monday: "Hazard did not train on Sunday but there is nothing serious. He was hit on Friday, but there is nothing to be worried about, we are going to assess the situation tomorrow, the reasoning is the same for Romelu Lukaku and the other players who played more than 45 minutes on Friday."

Chelsea return to action against West Brom on Saturday and bar any problems during this week's final round of international fixtures, Antonio Conte is set to have a fully fit squad available with the exception of Victor Moses.

A hamstring injury has sidelined the Nigeria international since October's 2-1 defeat to Crystal Palace, only returning to outdoor training last week.

The former Palace starlet is now wary of returning too soon after an injury that was more serious than first feared. He told Goal: "It was a bad one, it was a grade-three hamstring tear which is very bad so I have got to take my time. If I rush back then I could just fall back down again so it is about taking my time to be 100% fit to do what I am best at."
