Former Arsenal striker John Hartson has urged Kieran Tierney to leave the Emirates before the transfer window closes.
Newcastle have been strongly linked with a move for the Scotland international this summer.
The 26-year-old was not part of the Arsenal squad that managed to win against Nottingham Forest on Saturday.
Hartson told Go Radio: “I’m not surprised he (Tierney) is on the radar of several clubs, in particular a club that are going forward in the world in Newcastle… It hasn’t happened for him (at Arsenal), but he’s too good not to be playing every week.
“He was totally out of the fray at the weekend, and wasn’t even a sub. Arsenal went on and won 2-1. I don’t know if he’s injured or had a knock, but maybe that relationship with the manager is not quite there.”
