Competition for places is an important component of a winning squad, Willian has claimed after losing his place in the Chelsea team to Pedro.
The Brazilian was Chelsea's player of the year in last season's disappointing campaign, which saw the 2014/15 Champions finish 10th.
And despite scoring five goals in 22 appearances - his best ever league return for Chelsea - Willian has not started any of their last three league matches under Antonio Conte.
Pedro has been preferred alongside Eden Hazard and Diego Costa in the Chelsea front-line and has responded by netting in each of his last three appearances.
