CHRIS SUTTON: Three reasons why Liverpool's Champions League clash with Villarreal is NOT over despite the Reds' two-goal lead in their semi-final... Unai Emery's side have nothing to lose

I landed in Villarreal on Monday to a request - think of three reasons why Liverpool shouldn't think Tuesday's Champions League semi-final second leg is a foregone conclusion.

I'll be commentating on Tuesday night's game from the Estadio de la Ceramica and won't be turning up thinking this is done, dusted, over, kaput, goodnight Villarreal.

This is football - nothing is certain - so here are my three danger signs for Liverpool ahead of a very big night in Europe.
