Arsenal boss Mikel Arteta has sung the praises of William Saliba in France.
The Gunners meet Lens in the Champions League on Tuesday and was asked by local reporters about his France defender.
Arteta said: "When you look at how he's developing, the role that he's got in the team, the level and the consistency especially that he's shown in the last year or so, I think it's remarkable.
"I think you won't find many centre backs his age doing what he's doing.
"Credit to the players around him as well, the way they are guiding him, protecting him and inspiring him. And then obviously the qualities that he has, he has that presence, physicality and that composure to be a leader in the back line for a big club like us, so huge compliment to him."
