I don't think Chelsea needs Erling Haaland at that huge price tag, he is a good player and can bring a difference to Chelsea attack this season but spending that much on him with some players rumored to be a part of swab deal is not a good deal. I feel they should go for the likes of Robert Lewandoski or Harry Keane if its possible.
Chelsea has a good experience coach that can lead them to premier league victory, they should utilize this transfer window before it closes to build a team no team would want to play against.
Haaland isn't worse than Kane or Lewandowski. And by the way Tottenham wants 180 million EUR I think for Kane. Haaland would definitely perfectly fit into the squad of Chelsea. He is exactly the puzzle piece that is missing for Chelsea. Now some will say he first has to confirm that he is a good striker for another season, but seriously there are players where you simply know that they will repeat their achievements of last season or even trump it. Haaland is one of those players in my opinion who is almost guaranteed going to deliver again and again. He is not dependent on his character like Balotelli and he is not dependent on having a particular good day, hardly injured.
