"It's a tough one because you don't know what they're going to be like in February. If we were playing them now, it would be no problem but things might change," said Thommo on Sky Sports News after the draw.
"Having said that, it's still a game I fancy Liverpool to win. Rafa Benitez will be going home, and remember, Fernando Torres didn't get the opportunity to play against Atletico - his old team - earlier in the season. So, he'll be really looking forward to going back there and putting one over Real.
"I think Liverpool will have too much for them in the second leg at Anfield.
"It's a wonderful tie. I remember playing against them in 1981 - the all whites versus the all reds."
