Manchester City may be interested in Toni Kross. He is a great midfielder. However, Manchester City's midfield is already much stronger now. So I don't think it would be very profitable to add Kross, who is almost 34 years old, to the team. Talented midfielders like De Bruyne, Silva and Phillips are already in the City squad. If City want to plan long term then they should add a young talented midfielder to the squad. The addition of Toni Kroos to the squad may have strengthened City's performance. But I doubt if he can give service to the team for more than 2/3 years.
The new interests me and since Toni Kroos is a player that has worked with Pep Guardiola with Bayern Munich, moving to Manchester City have a good possibility of happening.
Being 34 means nothing. Toni Kroos, still has that ability to break down defense with his passes. That is something he can bring into Pep Guardiola's side. Besides, they've lost Gundogan and since left, no player has met his standards.
Pep Guardiola already brought in a yougin from Manchester City Academy he ( Lewis ,) is already doing well. Did had a good game against Arsenal but no matured enough in midfied.
