Atletico Madrid has accelerated its rebuild in La Liga, with a spending spree of nearly 100 million euros in transfers. The club is seeking a marquee signing to close the gap to La Liga leaders Barcelona and Real Madrid. According to The Sun, Atletico Madrid is monitoring Jack Grealish, who could leave Manchester City for a low fee due to his age. Grealish, who is already 30 years old, spent last season on loan at Everton and suffered an injury that kept him out of action for several months. Other clubs, such as Everton and Aston Villa, could also be options if a move to Atletico Madrid does not materialize. Coach Diego Simeone has already secured the signings of Morten Hjulmand for 40 million euros, Alejandro Grimaldo for 20 million euros, and Kang In Lee for 40 million euros. With the season about to start, clubs are working on their squads and many are waiting until the last day of registration to finalize their signings.
