Chelsea 2 Benfica 1 (Chelsea win 3-1 on aggregate):Chelsea had controversial referee Damir Skomina and goalkeeper Petr Cech to thank as they clung on against 10-man Benfica to set up a Champions League semi-final against Barcelona.

Card-crazy Skomina, whose performance in Arsenal’s last-16 exit against AC Milan led to a three-match ban for Arsene Wenger, was at it again at Stamford Bridge as the Blues reached the last four for the sixth time in nine seasons.

Frank Lampard opened the scoring after Skomina awarded a hotly-disputed penalty, one of several debatable decisions that included the first-half dismissal of Benfica captain Maxi Pereira.

The depleted visitors laid siege to the Chelsea goal at times and Javi Garcia set nerves jangling with an 85th-minute equaliser, but substitute Raul Meireles blasted home on the breakaway to seal a barely deserved home win in what was arguably the Blues’ worst performance under Roberto Di Matteo.

They gave away the ball so often, it was almost as if they were practising for being without it for the upcoming clash against Barca.

Chelsea have been a bogey team for the European champions down the years, but Pep Guardiola’s all-conquering side will hardly be concerned about facing them again on the basis of tonight’s performance.

Cristiano Ronaldo scored twice as Real Madridenjoyed one of their most comfortable passages into the Champions League semi-finals with a 5-2 victory over APOEL Nicosiaat the Bernabeu, to progress 8-2 on aggregate.

Ronaldo and Kaka scored before the break, the second from the Brazilian a wonderful curling effort from outside the area.

Gustavo Manduca had the noisy travelling support in full song after he broke away to pull one back for APOEL in the 67th minute, but Ronaldo with a free-kick and Jose Callejon quickly restored order.

Esteban Solari netted a penalty for the visitors but Angel Di Maria immediately lobbed a fifth for Real who eased into a semi-final meeting with Bayern Munich.
