Arsenal great Tony Adams has called on the club to tie Bukayo Saka down to a new contract.
Writing for The Sun, the former captain stated: "When Manchester City paid £100million to sign Jack Grealish 18 months ago, I couldn't believe that they didn't even try to buy Bukayo Saka.
"Even now I'm gobsmacked that Arsenal have been able to hang on to a kid who is already one of the best talents in the world.
"Hopefully, they will soon get Bukayo tied down to a lengthy new contract, so I can stop worrying.
"Like me, he's a London-born Arsenal fan who graduated through the academy and has the club in his blood. But they should never take that loyalty for granted.
"If Arsenal hadn't shown the level of commitment I was looking for at the time, I would have been out the door like a shot when Manchester United wanted to buy me in 1996.
"But they proved their ambitions by signing Patrick Vieira and Nicolas Anelka and that was good enough for me to sign on the dotted line.
"Playing in the Champions League next season will be a whole new ball game for this Arsenal team.
"At the moment they need Bukayo, Gabriel Martinelli, Martin Odegaard, Thomas Partey, Gabriel Jesus and Oleks Zinchenko playing every week because they have a team that almost picks itself.
"But I'm sure they'll give Bukayo that hefty new contract to keep him at the Emirates because they know he is irreplaceable.
"If there's a better player in world football at the moment, someone who both scores and makes goals, the only one I can think of is Lionel Messi. Bukayo is absolutely on fire and the reason Arsenal are top of the table."
