The Turkish Super Lig side announced they were in negotiations for both players on Saturday, with images circulating on social media of the pair travelling to Istanbul from Milan.

Mertens, a free agent following the end of his nine-year stint with Napoli, has penned a one-year deal with the club.

The Belgium international won the Coppa Italia twice during his time in Naples and was a member of the Red Devils squad that came third in the 2018 World Cup in Russia.

At 35-years-old, Mertens is yet to announce his international retirement and could yet feature at this year's World Cup in Qatar, where Belgium will be in Group F alongside Canada, Croatia and Morocco.

Torreira, meanwhile, had fallen down the pecking order at Arsenal, spending the past two seasons on loan with Atletico Madrid and Fiorentina. He has signed a four-year contract.

Capped 39 times by Uruguay, the midfielder will be aiming to represent the South Americans in Qatar – which sits in Group H with Ghana, Portugal and South Korea.
