Newcastle United boss Alan Pardew is delighted with the progress of Moussa Sissoko since his arrival.
Pardew — who celebrates four years on Tyneside next week — believes Sissoko has improved under his care following his £1.5million arrival from Toulouse in January, 2013.
The Newcastle boss said: "He is only a young player, 25, and he has already got 27 national caps for France. This is a guy who could win 50, 60 or 70 caps for France.
"He is a powerful player and he is better player now than he was back then.
"Don’t get me wrong, he had a great day then (against Chelsea) but he is better now and that is because he has more experience and a better knowledge of the Premier League.
"He has technically improved, without a doubt."
