The priority for Real Madrid right now is the need for Strikers. After Benzema's departure from the team, they still could not transfer a quality name to this region. They do not have big problems in defense, but of course, they may want to transfer to the defense. I think they should devote the budget to striker transfers instead. Joselu can be a good backup striker and needs a star striker.
Real Madrid are trying to bring in a quality striker who can replace Benzema role on their front lines, their efforts have yet to meet results due to the protracted transfer process for Mbappe from PSG. Real Madrid lack only a quality striker in their squad, Joselu is not the first choice in Ancelotti line-up even though he has joined on loan. Real Madrid are yet to find a suitable piece of the puzzle to fill the striker position, it looks like they will need to turn their attention to other players if Mbappe transfer process gets too complicated. Real Madrid might was tested again this season after they failed in the UCL and La Liga last season, a complete squad needs to be prepared in order to maintain the status of a team with a winning mentality.
