Villarreal will be without Marcos Senna for this week's Champions League return meeting with Arsenal because of injury.

The Spain international midfielder limped out of Saturday night's 2-0 home defeat by Malaga in the 80th minute due to a hamstring problem, leaving the Yellow Submarine with 10 players as coach Manuel Pellegrini had already made three substitutions.

It is not yet known how long Senna will be out for but, according to Villarreal's website, he will definitely miss Wednesday's Champions League quarter-final second leg at the Emirates Stadium.

Senna scored Villarreal's goal as they drew the first leg with Arsenal 1-1 at El Madrigal last week.
