Emmanuel Adebayor has already been given an advisory from team mate Kolo Toure and now coach, Roberto Mancini weighs in. The message is clear:
Cut down on the jiggery pokery and over the top goal celebrations. At the Eastlands, it led to a five match ban.
The Emirates match should feel like an alumni occasion with Adebayor, Kolo Toure, and Patrick Vieira on the pitch. But the match could be a potential tinderbox as both clubs have huge stakes in a win.
For many Arsenal fans, the return of their former players comes at a time when the club ended their Premiership chances with a mind numbing loss to Wigan last weekend and endured humiliating defeats against Spurs and Barcelona. They face City, now a rival who just ceded ground to Spurs on the all important fourth spot. Nerves could be a bit raw and celebrations might need to be tightly edited.
