Former Paris Saint-Germain star, Ronaldinho, has revealed why Lionel Messi is struggling at the club.

Messi joined PSG from Barcelona on a free transfer last summer after the Catalan club failed to renew his contract.

The Argentina captain has not really impressed at the French Ligue 1 giants.

The seven-times Ballon d’ Or winner was recently booed by PSG fans after their elimination from the Champions League at the hands of Real Madrid.

The Argentina international had a quiet game as PSG relinquished a two-goal aggregate lead in the second half of the second leg at the Santiago Bernabeu.

But Ronaldinho, a former teammate with Messi at Barcelona, believes the 34-year-old is struggling at PSG due to lack of ‘adaptation,’ adding that he has spent many years at Camp Nou.

But I think it’s difficult for Messi, who arrived this season after a lot, many years in completely different football, at a club that played the same way all the time.

It just lacks adaptation, but the rest will come naturally,” Ronaldinho was quoted by Sportskeeda as saying.
