Frank Lampard hailed the "infectious" Pedro after Chelsea's 2-0 win over Liverpool in the FA Cup fifth round on Tuesday.
Pedro has struggled for game time this season but helped Chelsea prevail at Stamford Bridge, where goals from Willian and Ross Barkley saw Lampard's side into the quarter-finals.
The Spaniard has made just 12 starts in all competitions this season, but Lampard praised the 32-year-old and said Pedro – who made his 200th appearance for the club – could be crucial for Chelsea late in the campaign.
"I agree he was outstanding in work ethic and players look up to him for what he has done. Always a goal threat," the Chelsea head coach told a news conference.
"Parts of the season have been difficult. He was in the team at the start, got injured and then got out of the team, but what he has shown, particularly in recent weeks, is a real desire in training, to look sharp, to be giving advice and giving the place a lift with his body language.
"He can be one of our most important players until the end of the season. He is an infectious player."
