The Finnish goalkeeper has been linked with Southampton, Crystal Palace and Swansea.
A Finnish international, Hradecky started his career with Esbjerg, before moving to Danish giants Brondby in 2013, and going on to make65 appearances for the club.
He has conceded 72 goals and kept 24 clean sheets in that time, but he has reached impressive heights this term, conceding just 23 goals in 27 games - and keeping a clean sheet at a better rate than one in two games.
He also has experience of Europa League football with Brondby, and is an international regular with Finland, having made his debut in 2010 and going on to total over 20 senior caps.
According to the report, Hradeck had a trial with Manchester United in 2010 and was offered a contract, but turned it down to guarantee consistent first-team football at club level.
Clubs in Italy and Russia are both also tracking him, whist Swansea City are also said to be keen admirers of the 25-year-old.
He has two years left on his contract after the end of this season, meaning Brondby will not be forced to sell their star goalkeeper. However, the financial rewards of the Premier League may be too hard for either the club or player to turn down should a formalised approach be made.
