Chelsea transfer target Rafael Leao has continued to drive speculation about his own future.
The 23-year-old stars for AC Milan at club level, while he is presently at the World Cup with Portugal.
Leao, who scored the final goal in a 6-1 drubbing of Switzerland in the round of 16, exchanged words with Chelsea star Reece James on social media.
The defender tweeted how Leao was among the toughest players he faced in his career.
Leao, who is likely to move on from Milan in the summer, replied: "My bro," alongside a handshake emoji.
Chelsea have been heavily linked to his signature since Todd Boehly took charge as the club's co-owner.
