Watford boss Quique Sanchez Flores has sought extra information from their medical staff on his players.

Since the manager's arrival in September, the head coach has seen several first team squad members spending their time in the treatment room.

"We still don't know exactly how is [Tom Cleverley's] injury," said Sanchez Flores.

"They are just checking, but it's a new one. Other players they are working on their recovery and they're improving, we will see in the future.

"I can't control what happened before we came here, so it's impossible to know, I don't know how is his story. We are working really hard with the medical staff about what happened in the pre-season, to have all the information about the injuries about everything because you know, we are one month here and one week - it's difficult to know exactly what happened with the story with these guys, these players, so for us we're interested in everything, every information we can take for the players.

"We know Cleverley has had problems with his heel before in the last years and we have some players here who have problems with their hamstrings and other players they didn't do pre-season and other players came here just after the season started, like Welbeck, like Sarr, they come pretty late to the team, so it's difficult to know exactly what happened.

"We don't have full control of the last four months, or five months to know what happened. We will try to investigate about what is the consequence, but I think we need to be clever."
