Chronicle Live have reported that scouts from all three clubs have been to watch the youngster, who is currently on loan at League One Bradford City.
Chronicle Live: Newcastle United loan watch: Alex Gilliead catches the eye for Bradford City... https://t.co/z0y9ke4j97— iNewcastleApp (@iNewcastleApp) November 28, 2017
The 21-year-old has impressed in West Yorkshire and is reportedly keen to step up a division, with Newcastle boss Rafa Benitez keen on the forward gaining some experience elsewhere.
Sunderland are a surprise entry in the race for the youngster, with new manager Chris Coleman looking at dipping into the loan market with the struggling Black Cats having little to spend in the transfer window.
Gilliead's loan spell at Bradford ends at the turn of the year and the second tier clubs are likely to jump straight in for his signature when he becomes available.
