Christian Benteke could return for Liverpool against Villarreal after travelling with the rest of the first-team squad to Spain, according to Sky sources.
Benteke returned to full training earlier this week after a month out with a knee ligament injury sustained on international duty with Belgium.
The 25-year-old, who last featured for Liverpool in the 3-2 defeat at Southampton on March 20, could be named among the substitutes for the Europa League semi-final first leg at the Estadio El Madrigal.
Benteke's return to fitness will be a welcome boost for Liverpool manager Jurgen Klopp, who lost Divock Origi to a "serious injury" during last week's Merseyside derby.
The Belgium forward has struggled to score on a consistent basis for Liverpool since joining the club from Aston Villa for £32.5m last summer.
Benteke has scored only eight times this season and last month accused Klopp of "ignoring him", leading to speculation that he could leave Anfield in the summer.
