Manchester City's Joško Gvardiol is at the centre of a transfer battle between Bayern Munich and Real Madrid. The Croatian centre-back has been linked with a move to the Allianz Arena, but the Bavarians have reportedly exited the race due to his price tag. Instead, Real Madrid has entered the fray, with interest in Gvardiol described as 'concrete'. Manchester City are pushing to keep their young star, with a contract extension offer already on the table. Gvardiol, 24, has been a top performer for the Premier League champions, and his signature would be a significant coup for any club. The smart money is on Gvardiol extending his contract with Manchester City, but Real Madrid could be getting desperate to make an impact signing. The transfer battle for Gvardiol is set to be one of the most closely watched in the summer transfer window.
