Club Brugge's young forward Antonio Nusa was the subject of a deadline day bid from Chelsea.
The attacker was one who the bosses at Stamford Bridge admire hugely after extensive scouting.
Per The Mail, the deal hinged on Chelsea being able to move Ian Maatsen on from the club.
Burnley offered 31.5 million for Maatsen, but he eventually decided to stay at Chelsea.
As those funds were not available, Chelsea had to change their plans with respect to Nusa.
They will likely go back in for the star in the winter transfer window, as long as his form continues.
