Koulibaly has arrived in London to complete his medical before flying to Los Angeles in the coming hours to be unveiled and join the squad. Raheem Sterling has spent one season with the team.
One down, two more defenders to go, probably Kimpembe or Koulibaly and then Ake. Let's not sign all three as that'll not give playings time to Levi Colwill and he's one of the younglings I'll love Tuchel to give a chance to. Look how giving Trevoh Chalobah, James etc some opportunity to prove themselves played out, Colwill should also be given same opportunity or we'll reject just as we have in the past since we're known for letting our young talents leave the club or go on loans.
James, Mount, and Chalobah all had chances and took them; they were never guaranteed first team football, so I don't understand why Colvil and his agent are asking the club for first team football based on a single brilliant season in the championship. We should sell and hire someone better. He's not even that unique.
Let's get it done with the defense quickly so some attention can be given to the attack. Yes we have secured sterling but is that enough to compete with Liverpool and Manchurian city for the title, not yet. We need a striker or better alternative to our current attacking force assuming we'll be using Havertz as a false 9 next season.
We are not always unlucky with strikers, so I believe that if we can bring in a creative midfielder and another winger, Havertz and Werner will be able to fill the number 9 role.
