Barcelona and Inter Milan have qualified for the Champions League semi-finals.

Playing at home, Barcelona beat Arsenal 4-1, thanks to a spectacular performance by Argentinian star Lionel Messi, who scored all four goals. Last week in London, the two teams drew 2-2.

In Italy, Inter Milan defeated CSKA Moscow 1-O, a week after another 1-0 victory in Moscow. Inter's only goal, scored by Dutch midfielder Wesley Sneijder, came after six minutes.
