The former Olympique Lyonnais defender moved to Portugal in the summer, but the move hasn’t quite worked out how the defender would have hoped.
Sarr was always predicted to be a player with a very bright future at the French club, but playing behind the likes of Samuel Umtiti and Milan Bisevac, he obviously questioned how much football he would be able to play at OL.
In the summer, Lyon signed Lindsay Rose from Valenciennes and further pushed Sarr down the pecking order and although he is still young, the central defender decided to make the move to Lisbon.
This season, Sarr has made 16 appearances for his new club, but only eight from the start and Charlton may offer the player an opportunity to play much more football than he has been able to play over the last two seasons.
Sarr should find it fairly easy to cope with the rigours of the English Championship, the defender stands at 1m 94, just under 6 foot 5, and weighs around 94kg. When you see him play, the first thing you notice is his impressive physical ability, although his size does not mean he is slow along the ground.
Superb in the air, a decent tackler, he definitely has a lot of developing to do over the next few years, but he has all the raw attributes to become an excellent defender.
The 21-year-old defender was part of the France squad that won the Under-20 World Cup, making five appearances in the competition, playing when Kurt Zouma wasn’t quite fit. He played 11 times for the Under-20 side and has since moved up to the Under-21s.
Any permanent move would be unlikely. Last summer he signed a six-year deal with the Portuguese giants with a release clause of €45 million, according to Mercato365. However, if he can help Charlton and they can help him progress, it could be an ideal move for everyone.
