Unexpected: K. Havertzas - a real contender to join "Arsenal" ranks © AFP

Kai Havertz could change teams in London.

"The Athletic" journalist David Ornstein was the first to report that Arsenal made an offer to Chelsea for the 24-year-old German.

K. Havertz himself aims to change clubs in this mid-season. He is actively interested in Real Madrid, who are willing to pay 40 million pounds sterling.

Chelsea wants as much as 70 million pounds sterling for the German national team striker.

It is worth mentioning that the "aristocrats" also want similar sums for Mason Mount. Tonight, the London club rejected the first offer from Manchester United. Its value was 40 million pounds.
