The Reds lost 3-1 at Anfield against Chelsea in the first leg of their quarter-final.
The Spaniard told Sky Sports: “The game is going to be much tougher now. We have to go to Stamford Bridge and beat them 3-1 or 3-0.
“But, as I said before, we are capable of winning at any stadium. We know we have to put ourselves back on track and try not to make the same mistakes.”
