A very sad day for me personally and for the club as a whole. Carrera probably made some tactical mistakes this season, but he never received any support from the club management.
We sold Quincy Promes, our best player, to Sevilla on August 31, the last day of the transfer window, and did not buy a replacement, and Samuel Gigot, our best defender (and the best CB in the league) torn his ACL. Moreover, our "captain" is too busy with his divorce and does not care about football any longer. Carrera had huge problems with player availability and had to suddenly play many youngsters in the starting eleven.
Moreover, the media and famous club veterans were very critical of Massimo since the summer of 2017, because they don't like that it was a foreigner who led Spartak to the first league title in many years. All in all, no support from the management, no good transfers, no support from the media. The fans backed Carrera up until the end, but it wasn't enough.
We fired Unai Emery in the very same way back in 2012 (the only difference was that he only spent a few months at Spartak), and he went on to win 3 Europa League titles with Sevilla and now coaches Arsenal. I am very sorry for Massimo and sincerely wish him all the best in the future. He never blamed referees, never criticized his players, was always respectful with the media (despite all the criticism). A class act.
