The French defender joined the Gunners for £27m in last summer’s transfer window, but was immediately loaned back to Ligue 1 outfit Saint-Etienne for the 2019/20 season to continue his development.
Having missed out on a French Cup final appearance at the end of last month, the teenager has been training at London Colney for the past week or so.
He was spotted by some eagle-eyed Arsenal fans in the build-up to the FA Cup final win over Chelsea – where he was involved in the post-match celebrations with Pierre-Emerick Aubameyang and Alexandre Lacazette.
With the 2019/20 season now complete for the north London outfit, attentions are turning towards the new campaign which gets underway later this month with a Community Shield clash against Liverpool.
That’s when Saliba could make his bow in an Arsenal shirt, but first, he will have to catch the eye of head coach Mikel Arteta during pre-season.
And judging by the footage of his first proper training session that has now emerged, he is already finding out exactly what the Spaniard’s demands are.
In a ‘Behind the scenes, William Saliba training special’ uploaded to the club’s official website, there’s a moment between Saliba and Arteta.
It’s unclear as to exactly what was said, but judging by the hand and body gestures, Arteta was showing Saliba how to receive the ball and what to do next.
Encouragingly for Arsenal, Saliba has explained that he is keen to achieve similar success in his career as Real Madrid star Raphael Varane after leaving France as a teenager.
“I have always had football in me,” Saliba told L’Equipe last month. “No matter how many people told me that I had very little chance of going pro, I never had a plan B or plan C. I stayed focused on my dream. Either we go for it or we fail.
“Now that I have made my dream of becoming a professional come true, I want to do things like Raphaël Varane, the best French defender: continue to breakthrough levels, play for the French team and win all possible titles.”
