Fabio Capello has warned Inter Milan to be wary of Liverpool's lethal counter-attacks when the two sides meet in tonight's Champions League showdown. Rafa Benitez's side hold a 2-0 advantage from the first leg at Anfield ahead of the San Siro clash.

"Liverpool are in good form," Capello, the England manager, said. "I watched them play on Saturday and they have taken three consecutive positive results, which has given them a boost in confidence.

"Inter will have to be careful not to concede a goal and not to be hit by their rival's counter-attacks because when Liverpool are given space they are lethal."

Capello believes Inter have a mighty challenge on their hands but has not ruled out their chances of progressing to the Champions League quarter-finals.

"In Inter I see the right spirit," he said. "There's the will to play a great game, but then of course you must be able to do this and always consider that you could give away a goal at any time."

However, the former Real Madrid manager will not be surprised if Liverpool become the fourth Barclays Premier League side to reach the last eight of Europe's elite club competition.

"The Premier League is a very rich tournament," he added. "It's full of star players, the best strikers such as Didier Drogba, Fernando Torres, Dimitar Berbatov and Emmanuel Adebayor play here.

"The top four clubs, and I would also include Tottenham in there, play a different type of football from the rest with a winning formula."
