The 16-year-old featured on a regular basis for his side's Under-18s last season and is also believed to have taken part in training sessions with the Under-23s over the summer.
According to the Daily Mail, Stoke are facing a fight to keep hold of the forward, who has managed seven goals in four appearances at Under-18 level this term, including a treble against Liverpool.
The report claims that Man United, Chelsea and Man City are all 'admirers' of the youngster, branded a "Harry Kane-type centre-forward" by Stoke's academy boss Gareth Owen.
Tezgel - part of the England Under-17s squad - scored twice against Man United Under-18s during a clash last month.
In total, the striker has netted 14 times in 27 appearances for Stoke Under-18s in the Under-18 Premier League.
