When Victor Valdes was coming towards the end of his time with the Catalan giants, having asked to leave at the end of his contract, the Slovenian keeper was touted as a possible replacement.
The Inter shot stopper was keen on the move to the five-time European champions, and at 29 years of age was about to enter the prime of his career.
A fee of around €23 million was to be paid to bring him across the Medditeranean, but the president of the club at the time refused to sanction the move. When asked publically about the move, Massimo Moratti said: "To Barcelona? No, Handanovic is staying with us."
At Barcelona, Andoni Zubizarreta then made the decision that another player would have to be found, and settled upon Marc-Andre Ter Stegen, who has been an undoubted success in the years since.
Claudio Bravoa and Ter Stegen were able to help Barcelona reach another European title in 2014. Given that they haven't won one since, this game could be a huge indicator of their chances of changing that.
