When Emmanuel Adebayor made it 2-0 against old club Arsenal yesterday, Gunners fans must have feared the worst as the Togolese international appeared set to repeat his Manchester City trick.
The 28-year-old's relationship with his former employers is fractious to say the least, with the troubles reaching their peak after a goal and celebration in-front of the visiting fans at the Etihad Stadium in 2009.
Whilst the reaction was of a much lower key at the Emirates, the feeling of when a former player makes you pay remains the same, and GMF have taken the opportunity to run through five other players who just had to make an impact against their old employer...
Carlos Tevez v Manchester United
The Argentine was a huge hit at Old Trafford, and the fans were desperate for him to stay when his 'loan' came to an end in 2009.
But, with problems over ownership and wages, United decided against signing the 28-year-old permanently, and local rivals Manchester City took their chance to make the massive signing.
After the 'welcome to Manchester' fiasco, Tevez just had to do the business on the pitch, and sure enough he scored twice in a Carling Cup semi-final clash that season, prompting Gary Neville to give his former teammate the finger.
Darren Bent v Tottenham Hotspur
The England international didn't enjoy the happiest of times at White Hart Lane, with comparisons to Harry Redknapp's wife and a Twitter rant over his protracted move away from the club just two high-profile moments.
He got his own back during the Stadium of Light clash in 2010 though, scoring twice (despite missing two penalties) in a 3-1 win that damaged his old employers chances of a top four finish.
Spurs still made the Champions League grade, but Bent continues to pop up against his old side with new employers Aston Villa.
Glen Johnson v Chelsea
Loaned to Portsmouth in 2006, Johnson was subsequently sold by Chelsea the following year, with the England right back spending two years at Fratton Park before making the move to Liverpool.
And, in November last year, Johnson showed the Blues what they were missing at Stamford Bridge, scoring a brilliant solo winner in the Reds’ 2-1 victory in west London.
Craig Bellamy v Liverpool & Manchester City
The Welshman is a serial offender when it comes to scoring against his old club, as both the Reds and Citizens have found to their cost on occasion in the past.
Bellamy spent a season on Merseyside in 2006-07, but after a season-and-a-half with West Ham, moved to Manchester City, scoring a goal tat Anfield which struck a major blow in the Reds chances of winning the title in 2009.
After falling out of favour under Roberto Mancini, he moved to Cardiff on loan and then Liverpool in the summer. And, sure enough, he struck against City in the League Cup semi-final to knock the Italian's side out of the competition.
And the ultimate nightmare return...
Denis Law v Manchester United
It was bad enough that Law was plying his trade for City, but United's nightmares got even worse when the Scot sent his old club down.
Law became a legend at Old Trafford alongside George Best and Bobby Charlton, but after leaving for the blue half of Manchester in 1973, he did the unthinkable at the end of his only season at the club.
In his last match as a professional, his backheel consigned the Red Devils to a 1-0 defeat and into the old Division Two. As it happened, United would have gone down anyway.
