As the season has finally finished the upcoming transfer window is going to be quite exciting from now on. I don't know top teams of the league would rush anything at the first times of it already. But some of them had better start looking for better players to put in specific positions to strengthen them. For example Liverpool and Manchester United come to my mind firstly.
Liverpool need a significant improvement for their midfield. They chased Bellingham transfer but he is about to sign for Real Madrid officially. I assume they will finalize Mac Allister transfer instead after this news. He is a really talented player to make Liverpool midfield more reliable.
As for Manchester United they also need some fortification in the central midfield as there aren't many options there. Sabitzer might be added to the team permanently maybe or they would look for another player. Most importantly they need a reliable striker and Kane is the strongest candidate for now.
Liverpool have to transfer a few players to the midfield. If Manchester United fail to sign Kane, they may repeat their performance this season. I don't think the Kane transfer is a mandatory option for them. However, Chelsea definitely need to make a good striker transfer. Star names like Victor Osimhen or Neymar could be good choices for them. I think the most comfortable team in the transfer period would be Manchester City. They have several alternatives in almost all regions. There is even such an example. Manchester City will most likely not sign a new contract with Ilkay. There are reports that Arsenal are seeing this as an opportunity. They are definitely the most comfortable team.
Neymar could be a good choice for Liverpool team. Because Neymar has great capabilities and skills in attack. As a result, Neymar will be able to create a wonderful combination with Salah to strengthen the attack.
