Milan have completed the signing of Mike Maignan from Ligue 1 winners Lille ahead of the departure of fellow goalkeeper Gianluigi Donnarumma.

The one-cap France international, who played a key part in Lille's stunning title success this term, has signed a five-year deal at San Siro for a reported €15million fee.

Maignan kept a league-high 21 clean sheets in 38 games – seven more than next-best Keylor Navas and Benoit Costil – and his save percentage of 78.9 was bettered only by the Paris Saint-Germain keeper among those to have played at least three times.

He made 180 appearances over six seasons for Lille in total and was named Ligue 1's goalkeeper of the year in 2018-19.

Milan announced the arrival of Maignan, who is part of France's Euro 2020 squad having made his debut in October, on their official website on Thursday.

The signing comes a day after Rossoneri director Paolo Maldini confirmed current first-choice stopper Donnarumma will leave next month when his contract expires after turning down fresh terms.

Donnarumma, a rumored target for the likes of Juventus, Barcelona and Manchester United, has been with Milan since 2013 and has been a regular for the last six seasons.

The 22-year-old kept 14 clean sheets in Serie A this season – a joint-high along with Inter's Samir Handanovic – to help Milan to a second-placed finish, their best since 2011-12 when also finishing as runners-up.
