Lionel Messi is dreaming of winning the Champions League again as he starts a new and unexpected chapter in his career with Paris St Germain.

Securing an elusive first triumph in Europe’s elite club competition will be the immediate target for the Argentina forward, who has won it four times with Barcelona, and his expensively assembled team-mates in a side which finished second in Ligue 1 last season.

However, president Nasser Al-Khelaifi also hopes his marquee signing will have a longer-term impact by persuading the in-demand Kylian Mbappe to stay, with the 22-year-old France international in the final 11 months of his contract.

Such is his association with the Catalan city, his home for more than 20 years, the diminutive forward has already considered the prospect of having to face Barcelona if PSG are drawn against them in the Champions League.

“Barcelona is my home, I have been there since I was a kid and I’ve lived so many things there,” he said.

“I don’t know if we are going to face each other – it would be very nice to go back to Barcelona.

“It will be very strange to play at home there in Barcelona with another shirt but it can happen and we will see.”
