The newspaper claims that the French striker was undergoing a medical at Bloomfield Road on Monday night and could figure against Manchester United tonight.
The deal is thought to run until the end of the season so that Aliadiere can prove himself in the top flight before Blackpool offer him a longer deal.
Aliadiere began his career at the world-famous Clairefontaine academy near Paris and was signed by Arsenal in 1997 when he was just 16.
Loan spells at Celtic, West Ham and Wolves ensued before he secured a permanent move to Middesbrough in 2007.
The fee was reported to be an inital £1.5million and he went on to score 11 times in 78 league games for Boro'.
The Express and Star also claims that West Brom could try to sign Aliadiere.
