Wrong sub. I know KDB needed to come off at that time due to his leg. But Ferna/Grealish would be a better option instead of Sterling. Either deploy Ferna or put Grealish to the left& move Foden to the middle.Because at that moment, you need to put on some midfielder to give more control in the midfield and Foden/Grealish could operate like a false 9. Sterling was a threat from behind but at that state, the opposite needed to chase a goal and they did not care the behind anymore. After the sub, Sterling had barely touched the ball for a long time and our midfield was a totally mess.
Actually I would start him instead of Gundo today. And sub Gundo for KDB, Grealish for Bernado by 50min mark. Use Sterling's energy to run at their defenders in the first half when the opposite still tried to maintain the attacking/defending balance.
All in all we know from the Euro final that Sterling was better than Grealish at many many things. But Sterling offered little when the team was pushed back and struggled to move up the pitch. Grealish, on the other hand, had the ability to use all his little dark arts to win a free kick and give the team a chance to breath.
In the next round, I hope to see Sterling as a starter and Grealish as an impact sub. Pep, get this correct! Even Southgate could see this!
