Watch Champions League online

Watch Chelsea - Barcelona, Champions League semi-final second leg, online

You can watch Chelsea take on Roma and Liverpool's visit to Atletico Madrid in the Champions League online.

The Sky Sports website will have coverage of the games, which cost £2 to watch. The games kick off at 1945BST and can only be accessed by surfers in the UK.

Chelsea have several players out injured though have been in good enough form to hit the summit of the Premier League table.

Boss Luis Felipe Scolari is without Michael Essien, Michael Ballack, Ricardo Carvalho, Didier Drogba and Joe Cole. However, Deco may feature after his recovery from injury.

Opponents Roma were beaten 4-0 at home by Inter Milan at the weekend and also suffered a shock defeat to Romanian opponents Cluj earlier in the Champions League group stage.

Liverpool's Fernando Torres won't be available to face his former club and won't even make the trip to Madrid as he continues his recovery from injury.

Martin Skrtel is also out for the visitors but Yossi Benayoun and Robbie Keane should be fit.

Atletico's side includes former Manchester United forward Diego Forlan and Florent Sinama-Pongolle, an ex-Liverpool player.

However, their league form has recently been patchy and the club is surrounded by rumours that beleaguered Tottenham boss Juande Ramos may be about to take over.
