Lionel Messi has joined Paris St Germain after his emotional departure from Barcelona.

Messi bid a sad farewell to the Catalan giants after "financial and structural obstacles" prevented him from signing a new deal at the club.

The six-time Ballon D'or winner was heavily linked with exiting the Catalan giants last summer but, after staying on for one more season, the club revealed he would be leaving, with PSG always leading the race to sign him.

Here, the PA news agency reviews the eventful last 12 months of Messi's time at the Nou Camp.
