Schuster branded the Premier League leaders as ‘unattractive’ and ‘ugly’.
He told The Sun: “Liverpool rely on an unattractive style of football. They are an ugly team to play.
“Look how they really gave Barcelona a going-over last season, when they knocked them out of the Champions League. That’s what I mean.
“I want the Champions League because it’s a trophy I was so close to winning as a player with Barcelona under Terry Venables.
“We reached the final in 1986 and lost to Steaua Bucharest on penalties. Then I also lost in the semis when I was playing for Real Madrid.
“I would rate Liverpool, like AC Milan, as our major rivals for the Champions League this season. They are clubs which never tire of winning big trophies again and again.
“But my personal preference, if I could choose the best of all our European rivals and transplant them to Madrid, would be to take the Manchester United attack and graft it on to the Chelsea defence. That would be the perfect combination.”
