Pedro has pointed the finger at Tottenham for copying Chelsea’s 3-4-3 formation.
Pedro has flourished for Chelsea since Antonio Conte switched to the new system midway through their 3-0 defeat to Arsenal in September.
Since then the Blues have won eight out of nine games – losing only to West Ham in the EFL Cup.
Tottenham have also utilised the 3-4-3 formation under Mauricio Pochettino while Pep Guardiola has also experimented with it at Manchester City.
And that has not gone unnoticed by Chelsea winger Pedro, who has scored three goals in his last seven matches.
“It’s obviously helping and we’re getting to understand the system more and more,” Pedro told Chelsea’s official website.
“What’s interesting is that other teams are now using that system as well, and they’re adapting to the way we’re playing and changing their system accordingly.”
Pedro and Chelsea take on West Brom on Sunday (12pm) as they look to extend their three-point lead at the top of the Premier League.
“The new challenge for us is to keep overcoming that, but the immediate challenge in front of us is the game against West Brom,” Pedro, 29, added.
“They are seventh in the league, they’re having a good season and it will be a difficult game.”
After a disastrous first 12 months in England with Chelsea, Pedro is delighted to see things going his way under manager Antonio Conte.
He told: “I definitely haven’t been on a run like this here at Chelsea and I can’t think of one in my career that’s been this long.
“Last year we didn’t manage to win games on the bounce so let’s hope we can keep this going.”
Conte has come in and turned a mid-table side into genuine title contenders once again.
