ABU DHABI (Reuters) - Lewis Hamilton has admitted he 'massively underestimated' how hard his long goodbye to Mercedes would be ahead of an emotional final race for the team in Abu Dhabi this weekend.

The 39-year-old seven-times world champion stunned Formula One in February when he announced he was leaving Mercedes, who have supported him since his days in go-karting, for Ferrari at the end of the year.
