LONDON, May 19 — Sonia Bompastor praised Chelsea’s new celebrity backers after multi-millionaire businessman Alexis Ohanian and his wife, tennis great Serena Williams, flew over for their FA Cup final triumph yesterday.

The Blues’ 3-0 win over Manchester United saw French coach Bompastor complete a domestic treble in her first season in charge, with the west London side the first team to go through a 22-game Women’s Super League season unbeaten as well as winning the League Cup.
