Adams is enjoying the most prolific campaign of his career under Garry Monk, scoring 19 goals in the Championship to turn the Blues into dark horses for a place in the end of season play-offs.
As a result, the 22-year-old has been linked with a number of Premier League sides in recent weeks with TEAMtalk adding five more to the list.
It is understood that Spurs and Everton have sent scouts to watch Adams in action of late. Bournemouth, Crystal Palace and Newcastle United are also understood to be keeping tabs on a player who started his career as a winger.
The report adds that Birmingham are open to selling Adams in the summer but they want £20 million for a player who is under contract until 2022. The Mail claims they turned down a £12 million bid from Burnley on the final day of the January transfer window.
Interestingly, Adams made his name in an EFL Cup clash against Tottenham in January 2015, scoring twice inside just five minutes in a dramatic semi-final at Bramall Lane.
