Willian form may trigger Mata's Chelsea exit

LONDON (Reuters) - Juan Mata could be on the way out at Chelsea and, despite Jose Mourinho saying earlier this season he preferred Oscar in the No. 10 role, it is the form of another player that has led to the Spaniard being ignored recently.

Oscar's fellow Brazilian Willian made a slow start to the campaign after spurning a move to Tottenham Hotspur at the last minute in favour of a big-money transfer to Stamford Bridge from Russians Anzhi Makhachkala in August.
