Kalvin Phillips shouldn't have left Leeds if he wanted to be a regular starter. Because it was obvious that his job was going to be really difficult about taking the shirt in the starting lineup. He is actually a talented defensive midfielder. But when there are so many solid alternatives like him it is harder to be a regular as a starter.
Not being able to play regularly and for so much time would probably affect his chance of being called to England national team as well. I assume he will end up with signing for a mid level team in the near future. It would be better for him if he is ambitious to play more often.
Actually Kalvin Phillips not leaves Leeds United if won't loss regular position exactly Manchester City have many top midfielder and make difficult for Kalvin Phillips keep in the regular position on every games. Have interested rumor from Newcastle United want to sign him after suspend of Sandro Tonali until the end this season and Newcastle need recovery on midfielder position. I think this good opportunity for Kalvin Phillips leaves Manchester City in winter transfer window opening because he still loss compete to be Manchester City regular players although he was be second season with Man City.
Actually problem for top players not comfortable although bigger payment salary with top teams but difficult with regular position, seems Kalvin Phillips will priority with another team who guarantee with more minutes playing and leaves Manchester City as soon possible if have any interested teams want to sign him.
It looks like Kalvin Phillips wont be wrong if he chooses Manchester city in the future transfer market because I think it is an opportunity for him to be part of the Manchester city team. We can see that Manchester city last season won many titles in all competitions including the champions League, he definitely want to to be part of this great team because not all players have the same opportunity to get an offer from a great team like Manchester city, even though they dont have enough minutes to play and it is not necessarily possible that the team will change when he arrives.
