On a freezing February night in London in 2006, Samuel Eto'o's late header secured a 2-1 win for Barcelona in their Champions League clash with Chelsea. A 1-1 draw two weeks later at the Camp Nou saw them safely into the quarterfinals and they would go on to win the trophy for just the second time in their history.
It was the beginning of a golden era for the club -- they won the Champions League three more times in the decade since, alongside plenty of other silverware -- and watching in the stands at Stamford Bridge was Ferran Soriano.
