Saints are still trying to reshape their squad and are looking to bring in more players before the transfer window closes tonight.
Southampton boss Russell Martin is looking to add more firepower to his arsenal and he has a few attackers in mind.
Belgian side Club Brugge’s winger Buchanan is a player he likes and the Championship outfit are now in the mix to sign the Canadian attacker.
La Liga side Atletico Madrid are also amongst the clubs who are in the race to sign Buchanan this summer.
And, according to Belgian journalist Sacha Tavolieri, the Belgian side have been approached by an unnamed club for Buchanan.
However, it has been claimed that a deadline-day move for the winger is not guaranteed as Club Brugge have struggled to identify a proper replacement for him.
It has been claimed that a deal is likely to be dependent upon whether Buchanan is prepared to leave Club Brugge in the coming hours.
