Wigan Athletic winger Victor Moses final audition in front of Chelsea chiefs on Sunday swung a move in his favour.
The Daily Mail says Moses was outstanding for Wigan during their 2-0 defeat by Roberto Di Matteo's side at the DW Stadium in last weekend's Premier League opener.
That performance convinced Di Matteo, as well as Chelsea technical director Michael Emanalo and owner Roman Abramovich, to meet Wigan's asking price.
