He started against Brentford. Then not since, but he is ready to start."Ten Hag also insisted that he would not be taking the competition lightly, as he added:"We have to win every game. We want to win every tournament, so we take everything seriously. We not only have a team, we have a squad, that is clear. It's the mentality what Manchester United need. I cannot keep them all happy every game, but everyone gets their game-time if they perform well."He added:"We need everyone because we have a lot of games to cover with the internationals, the cups, and Premier League. When a team is acting well, when players are acting well, then you stay in.. For players not in the team, they can at any moment come in, do the job and maybe do better than the ones who are in."Cristiano Ronaldo@CristianoIt's always good to be with you! 🏽 #alwaystogether34455117379It's always good to be with you! 👏🏽 #alwaystogether https://t.co/QdpkKcuS0F
