"you score the winner against city and I'll get you on the back off my manchester united top # dealornodeal # BA19"
To which Ba simply replied with;
"Deal."
Now granted Ba isn't exactly putting up anything himself in the wager and won't lose anything if he doesn't score but for United fans, could we see a legion of BA 19 on the backs of the Red Devil shirts next season, giving out their gratitude to the Toon striker if he were to score the winner. As The Sun say who first reported this story, maybe the Man United fan would have been better making the wager with Papiss Cisse.
