Frank Lampard is expecting an "emotional return" for former Chelsea teammate and Aston Villa assistant John Terry at Stamford Bridge on Wednesday.
The pair faced off in the Championship last season when Lampard was in charge with Derby.
But Wednesday will be the first time they clash in the same stadium where they won numerous titles together as players.
"I went up against him twice last year and we obviously get on very well and I've got huge respect for him and the work that him and Dean Smith have done there with Aston Villa," Lampard said.
"So I think it's more about John and probably the reception he will quite rightly get from the Chelsea fans. He was the most decorated captain, greatest captain, won everything, feels the club - everybody knows that.
"The fans will certainly show their appreciation and I'm sure it will be pretty emotional for John. He deserves that moment and I will certainly be pleased to see his face back at the Bridge."
