Paris Saint-Germain has signed winger Ezequiel Lavezzi in a transfer from Napoli reportedly worth up to €30 million.

The Argentine arrived in the French capital on Sunday and signed a four-year contract after passing a medical on Monday.

French media say the $37 million move had been expected for weeks, and both clubs confirmed the news with Napoli thanking ''Il Pocho'' for helping the team ''reach important goals, both in Italy and in Europe.''

One of Napoli's key players, Lavezzi was a member of the Serie A side's ''Three Tenors,'' along with Edinson Cavani and Marek Hamsik.

Lavezzi decided to leave Napoli after the club failed to qualify for the Champions League. He broke down in tears after helping the team win the Italian Cup in his final game.
