Manchester City have already suffered a big blow in the summer transfer window and the aim for the rest of the summer will be to suffer no more.
Losing Ilkay Gundogan could be significant. City have gotten used to saying goodbye to legends and have always survived when doubters thought they were lacking in certain positions, but Pep Guardiola hasn't lost a player like his last captain.
While the likes of David Silva, Sergio Aguero and Vincent Kompany were all on the decline and the time was right to move on, Gundogan is still playing the best football of his career and was instrumental in the treble triumph.
Mateo Kovacic has been signed but it's impossible to know if he'll be able to fill the void left behind. City don't view the Croatian as a direct replacement and proved they still want another midfielder after making an approach for Declan Rice before being priced out.
