Striker
We'll need a striker to replace Ronaldo, either in January or summer. Not necessarily a big name but someone who will compliment the players we have, especially Bruno, who has a great partnership with Martial.
Goalkeeper
I feel our dominance on the ball over the last few games have come as a result of De Gea being better with the ball at his feet; however, I feel we need a top class ball playing goalkeeper if we are to play out from the back more often.
Right Back
As good as Dalot has been, I feel like we are already overplaying him. Unless we're going to play Williams or Wan-Bissaka (I know both are currently injured) we must find a right back in January to rotate with Dalot.
Centre Midfielder
I believe Casemiro and Bruno are the mainstays in our midfield. I do think that we could do with a proper box to box number 8, though. A mezalla type, who has the energy to run in behind and create overloads out wide.
If you look at the current options, we have Fred who will bring all the energy off the ball and is a pressing machine. We then have Eriksen, who, whilst he doesn't bring the same amount of energy as Fred, brings a much needed calmness and creativity to our midfield. What we need to find is a player who can give us both of those.
Centre Back
ten Hag prioritized a left footed centre back when he came in. Not only is Martinez good on the ball, but him being left footed gives us that much needed balance to our back line. Therefore, I believe we should be targeting a young left footed centre back to deputize for Martinez.
