Galatasaray have signed Colombia striker Radamel Falcao on a free transfer and have completed season-long loan signings of Brighton forward Florin Andone and Southampton midfielder Mario Lemina.
Falcao, 33, was reportedly greeted by 25,000 fans in Istanbul on Sunday as he arrived to complete a move from Monaco.
He joins the 22-time Turkish champions on a free transfer.
Galatasaray say they have paid a loan fee of 700,000 euros to sign Andone.
The Romanian joined Brighton on a five-year deal from Deportivo La Coruna in June 2018.
