The 22-year-old has been attracting plenty of attention from the Premier League.
The Lorient defender is being monitored by the Premier League pair as well as Ligue 1 side Paris Saint-Germain, The Sun claims, and a move for the 22-year-old may be about to become even more appealing to those sides interested in bagging his signature.
The Sun suggests that with the France-born Portugal international's contract about to enter its final 12 months, he may be available for a smaller fee this summer than a player with his talent would normally command, otherwise Lorient risk losing him for nothing at the end of next season.
While the defensive side of Guerreiro's game arguably needs attention, it is hardly surprising that he has caught the eye as he boasts a tremendous amount of talent going forward.
His ability to run with the ball and the quality of his passing means that he would undoubtedly enhance both the Gunners' and the Reds' attacking depth and give opponents more problems to think about.
And with his asking price reportedly around £6m, a move for the youngster is now surely something of a no-brainer.
