Chelsea were unsure about the quality of Brentford and Tottenham Hotspur target Antonio Nusa in the January transfer window.
Brentford were on the verge of signing the winger in the January transfer window until they discovered a problem in his knee during a medical.
A deal worth €37m is in place between Brentford and Club Brugge and it has been suggested that the knee issue is nothing major.
However, Brentford are reportedly not sure about spending such a huge sum on Nusa in the summer, opening the door to other Premier League sides, which may include Tottenham, who also held talks to sign him in January.
Chelsea were also interested in the winger in January, but according to Belgian daily Het Laatste Nieuws, the Blues were unsure about his overall quality.
The west London club were considering moving for him before deciding against trying to sign Nusa.
There are doubts about his talent ceiling at Chelsea and the club kept their powder dry in January.
Nusa has the latter half of the season to convince his Premier League suitors about his fitness and quality ahead of next summer.
