Get to know the final four teams that lock horns this week in the semi-finals of Europe’s most illustrious tournament, the UEFA Champions League.

Barcelona

Since the inception of the Champions League in 1992/93, there has never been a team to have won Europe's top honour back-to-back. Looking back, the last team to have done so was AC Milan in the 88/89 season when the competition was still known quite simply as the European Cup. This year, together with the likes of Europe's most lethal player, Lionel Messi on board, FC Barcelona are up for the challenge of making modern European club history by winning the double.

The story so far

The Catalans began its journey with a 2-2 draw at home against seven-time UCL champions AC Milan. Since then, they've gone on to greater success in the league, finishing top of their table in the group stages which had the likes of AC Milan, Viktoria Plzen and BATE Borisov in it.

Barca later demolished Bayer Leverkusen in the final 16 with a crushing 10-2 aggregate score line. Inter were next to face the Catalans, and after a goalless first leg, Barca pressed on the advantage at home, and won the round 3-1.
