Frank Lampard proved the undoing of Chelsea with the equalising goal for Manchester City. Here are five others who returned to haunt the clubs who once paid their wages…

Denis Law, 1974
Man United legend Law returned to Old Trafford with Manchester City on the final day of the 1973-74 season and backheeled a late winner as United were relegated.

Mo Johnston, 1990
The ex-Celtic striker signed for Rangers, becoming only the second to have played for both Glasgow sides since WW2 – and netted the only goal in an Old Firm game.

Emmanuel Adebayor, 2009
The Manchester City striker ran the entire length of the Etihad Stadium pitch to celebrate a header against his former club Arsenal in front of their fans.

Zlatan Ibrahimovic, 2010
The Swede swapped the blue half of Milan for the Rossoneri and netted the match-winning goal in a 1-0 derby victory at the San Siro.

Robin van Persie, 2012
The former Gunners’ favourite took three minutes to punish his former side, netting the opening goal in a 2-1 Premier League success at Old Trafford.
