Ex-Chelsea winger Paul Canoville says Arsenal fan Lewis Hamilton should stay loyal to his own team and has backed Todd Boehly's bid to buy the club.
Canoville said he is "a huge fan" of Hamilton and tennis star Serena Williams, who are both involved in Sir Michael Broughton's bid for Chelsea.
But the allegiances of the seven-time F1 champion and 23-time Grand Slam tennis champion are a problem for him.
He added that "Serena is on record saying she supports Real Madrid".
"I will always support Lewis in everything he does in F1, he is the greatest driver ever in my opinion," said Canoville.
