Arsenal face being crowded out in the battle for Benfica attacker Andrija Zivkovic.
Arsenal boss Arsene Wenger has personally requested their scouts to keep a close watch on Zivkovic this season.
But TMW says he now faces stiff competition from across Europe - including Manchester United.
Borussia Dortmund, Juventus and AC Milan are also challenging for his signature, with all making contact with Benfica about Zivkovic's price and availability.
The 21 year-old scored in victory at Portimonense last weekend.
