The midfielder believes PSG are stronger following the signing of the signing of the Argentina star and is certain he will be a success
Di Maria made his PSG debut in Sunday’s 3-0 win over Monaco at the Stade Louis II and provided an assist for Ezequiel Lavezzi after Edinson Cavani had scored twice.
“He is a great player. Everyone knows it,” explained Motta.
“He is a great player with experience and great quality. I’m sure he will show his quality for the team. With him, we are stronger.
“We have to thank the club for signing a player of the level of Angel. I think it’s good for Paris Saint-Germain.”
Motta ended speculation over his future last week by agreeing a new two-year extension to his deal in the French capital.
“I’ve always been quiet and now I am more so because I know that I will stay at Paris Saint-Germain for two more years,” he added.
“Along with my team-mates, I will try to give 200 per cent.”
