William Saliba has already set some high standards at the beginning of his Arsenal career, although there are a couple of factors that are leading to question marks with regard to his involvement against Newcastle United on Tuesday night.
Since returning in the summer following a successful loan spell with Marseille, the 21-year-old has become a mainstay in defence for Mikel Arteta's side. Forging an impressive centre-back partnership with Gabriel Magalhaes has provided a platform for the Gunners to mount a Premier League title challenge.
Whilst there have been some hiccups with regard to Saliba's performances along the way - which is expected given his age - since a man-of-the-match display on his competitive Arsenal debut against Crystal Palace, he was excellent in wins over Tottenham Hotspur and Chelsea to justify the early season praise and excitement amongst the fanbase.
