Guedes facing two months out

The 22-year-old Portuguese international has been struggling with a pubalgia, commonly known as a sports hernia.

"The player will return to Valencia in the coming days to start the recovery work that, according to the initial forecast, is around two months," said the Valencia statement.

Guedes, who joined Valencia from Paris Saint-Germain in the summer after a successful campaign on loan at the Mestalla last season, originally sustained the injury during a 1-1 draw with Barcelona in early October but has played in matches since, including the 2-0 defeat at Real Madrid at the start of the month.

Marcelino's Valencia have been disappointing so far this season, having finished fourth in La Liga to qualify for the Champions League seven months ago.

They sit 15th in the Spanish top flight after winning just three of 15 matches, and dropped into the Europa League last 32 after finishing behind Juventus and Manchester United in their Champions League group.
