Sunderland are preparing to make a move for Mariano Troilo, with the Italian club open to a £26m sale. The 22-year-old defender has been identified as a key target by Regis Le Bris, who is looking to strengthen the squad for the upcoming season. According to reports, Sunderland are in pole position to land Troilo, who is yet to reach the peak of his powers. The signing would be a significant boost for the club, who are looking to build on their recent success. Sunderland have also been linked with a move for Celtic's Arne Engels, who is reportedly open to a Premier League switch. The midfielder would be an excellent addition to the squad, particularly with the Europa League in mind. With European football to offer, Sunderland are attracting ambitious names, including Khephren Thuram, who could be on the move in the coming months. The Black Cats are set to face competition from rivals Newcastle United, but their European pedigree could yet lure the Frenchman to the Stadium of Light. Sunderland's transfer business is yet to commence, but the club is expected to make a number of significant signings in the coming weeks. The signing of Troilo would be a statement of intent from the club, who are looking to make a push for the top of the Championship. The defender's arrival would also provide a significant boost to the squad, who are looking to build on their recent success. Sunderland's fans will be eagerly awaiting the arrival of Troilo, who is expected to make a significant impact at the club.
