West Brom are keen to strengthen at the back, despite making plenty of additions in that area already this summer.
Darren Moore’s side are now said to be lining up a £5 million move for Ayling, who has become a really reliable figure at Leeds.
Ayling has been one of Leeds’ star performers since Marcelo Bielsa took charge, with his performances over pre-season and on opening day catching the eye.
Leeds selling Ayling would be a major shock, but a move to the Hawthorns could appeal as West Brom already have Kyle Bartley.
Bartley and Ayling were part of Leeds’ defence two seasons ago, and have become great friends, with the pair even going on holiday together earlier this summer.
If West Brom did manage to buy Ayling off Leeds, it is likely that Andrea Radrizzani would come in for criticism for selling him from the Elland Road crowd.
