The promising goalkeeper has attracted the attention of several top-flight clubs.
The 20-year old broke into the Latics' first team last season and has since established himself as David Dunn's number one.
The ESPN. report claims Aston Villa scout Tony Coton has watched the young stopper on several occasions - as have scouts from other unnamed top-flight clubs - and Oldham are bracing themselves for the offers which are sure to arrive in the near future.
ESPN quote the player’s agent, Clive Hart, as saying the following: "It would be no surprise that other clubs are looking at Joel as he has been superb for Oldham since coming into the side.
“Joel is enjoying his football at Oldham and is happy to be playing so he can continue his development.
"It is flattering to be linked with top clubs, but Joel is focused on doing his best for Oldham and we will see what happens regards his long-term future."
Just how long Coleman remains content at the League One club once the offers come flooding in is another matter entirely, and Villa’s desire to bolster their options between the sticks is no secret.
The Villans parted ways with Shay Given over the summer and former Norwich City ‘keeper Mark Bunn was drafted in as a stop gap.
Doubts have also arisen over the long-term future of first-choice Brad Guzan and so a move for a young prospect, of the ilk of Coleman, makes sense.
