One forgotten man and one key midfielder trained today.
With the way in which they disposed of Borussia Dortmund in the quarter-finals, netting three second-half goals to stun the Germans, Liverpool will fancy their chances of reaching the final by beating the Spanish outfit tomorrow night.
The visit of Villarreal surely comes too soon for the fit-again duo - especially Ings, who has not yet played under Klopp, having been absent since October - but their return would certainly stand the team in good stead if they should reach the showpiece in Switzerland on May 18.

With striker Divock Origi out injured, Klopp is short on viable striking options. He does not appear to fancy Christian Benteke or Daniel Sturridge up top, and a question mark still hangs over Roberto Firmino to some extent, leaving Ings as a another option, despite a lack of fitness at the moment.
Meanwhile, midfielder Can is arguably the most improved player on Merseyside since Klopp replaced Brendan Rodgers in October, and he might be vital if they reach the final, where Shakhtar Donetsk or Sevilla may await.
