“Think carefully before you sign him”- Abramovich warned about possible €90m summer deal

Borussia Dortmund striker Erling Haaland is a key transfer target for the Blues this summer.

However, Chelsea have been warned signing Erling Haaland could be a “disaster” if the chemistry in the team isn’t right. This is according to Chelsea legend Frank Leboeuf.

“Haaland is a beast. Of course it would be a plus for Chelsea,” Leboeuf told Sky Sports News. “But now you have to think financially and economically, and you also have to also think and make sure your dressing room is going to be following the coach.

“If you put Haaland (in the team) you lose [Olivier] Giroud, but you might lose [Kai] Havertz, you might lose Werner as well. What about [Christian] Pulisic? Where are you going to play [Hakim] Ziyech?

“That is an equation that you have to make sure is going to work and that the results are going to be good for the club.

“You can add talents, that is not a problem. But you have to make sure the chemistry works.

“Otherwise it is going for disaster. Having only talent doesn’t make sure you are going to win something.”
