Roberto Di Matteo played down the talk of a revenge mission as Chelsea visited Gelsenkirchen to take on his Schalke side - but it was embarrassment that greeted the Italian as the Blues eased into the knockout stages of the Champions League.
Current Chelsea boss Jose Mourinho insisted in the build-up to this clash that his side needed to keep up their good form to avoid blowing their place at the head of Group G and ending up playing in the Europa League.
But he need not have worried as his ruthless side blew Schalke away - dominating throughout and eventually running out clear 5-0 winners.
The Portuguese was also steadfast that he did not want to talk about Di Matteo's achievements at Stamford Bridge but did question whether the side the 44-year-old led to European Cup success was a good one.
The two exchanged a cursory handshake before kick-off that lacked the warmth of a meeting of friends but that was in stark contrast to the travelling Chelsea fans, who sang Di Matteo's name as the game got under way - and that was as good as it got for their former midfield favourite.
Chelsea stormed into a lead as Schalke goalkeeper Ralf Fahrmann did well to turn a Diego Costa effort behind for a corner in the opening minute, only to see Terry head home Cesc Fabregas' set-piece.
A lull in play allowed Chelsea's fans to burst back into 'One Di Matteo' chants and this time the Italian gave them a wave of appreciation as his side continued to grow into the contest.
But they were two down before the game was 30 minutes old as Willian exchanged passes with Eden Hazard before firing a low shot which Fahrmann failed to keep out as the ball squirmed underneath him.
Schalke's fans soon turned on their side as they were caught dawdling on the ball and Costa intercepted an under-hit back pass but was unable to keep his balance as he tried to round Fahrmann and was eventually crowded out.
But once again the respite was short-lived as Fabregas delivered another corner into the danger area and Kirchhoff mistimed his headed clearance under no pressure from a Chelsea shirt and it flashed into his own net to put the visitors well and truly in command.
Di Matteo altered both his system and his personnel at the break and, although Schalke were able to keep better hold of the ball, it was Chelsea who were still carving out the better chances.
Branislav Ivanovic fired a well-struck volley wide having been found free inside the box by a clever Willian pass before Costa, still without a European goal for Chelsea, fluffed his lines when played in by Oscar.
That was the last piece of action for Costa as he was replaced by Drogba, the man who scored the decisive penalty in the final against Bayern Munich, shortly afterwards.
The experienced forward netted his first chance of the evening as both he and Willian beat the offside trap and the Brazilian unselfishly squared for Drogba to tap home.
Fellow substitute Ramires headed home just 73 seconds later as Drogba turned provider.
Chelsea decided enough was enough at five and saw out the remainder of the contest to leave Mourinho happy with progression.
