Eagle eyed Arsenal fans believe that they saw William Saliba in the background of snap that showed Mikel Arteta’s side being put through their paces in training on Tuesday.
The Gunners are gearing up for their season finale in the form of the FA Cup final against London rivals Chelsea on Saturday (5.30pm).
Saliba cannot play a part in the showpiece as he spent the season on loan back at St-Etienne and is not registered to play in the FA Cup this year.
But now the centre-back has returned to Arsenal from the Ligue 1 club it does appear that he is taking part in training sessions.
Although it hard to be 100 per cent certain that the blurry person in the image is indeed Saliba, he certainly resembles the 19-year-old centre-back.
Arsenal fans reckon they spotted William Saliba training with his new team-mates
The £27m defender recently dyed his hair a distinctive copper colour, a look which the player in question certainly appears to be sporting.
The training pic shows Dani Ceballos taking a corner in the foreground and a number of players jostling for position in the penalty box.
Saliba, who was given the no. 4 shirt last week as Arsenal released their new home kit for the 2020/21 season, had been training alone in recent days.
The Frenchman spoke recently of his happiness at his Arsenal move, telling L’Equipe: “I fell for Arsenal from the start. A number of French players have been there.
Is this William Saliba?
William Saliba trained with Arsenal earlier this season
“Arsenal has not been at the top of its game for the last three, four years – but like Saint-Etienne, its badge, its history and its fans made me want it.
“I have a crush on Arsenal. I had no hesitation [in signing for them].”
He did, however, admit to feeling ‘like a robber’ after leaving Saint-Etienne ahead of their Cup final against PSG after Arsenal refused to extend his loan.
