Who do you think will win? To be honest, no one wants to see Piers Morgan win...
In fact, Neville has already had a bet with his former rival and now Sky Sports Colleague, Jamie Carragher over wearing Man United shirt with his name on it.
And now, Neville is back with another bet, this time in the wake of Man United humbling defeat at the hands of bitter rivals Arsenal.
The Gunners managed to shellshocked Louis van Gaal's side, with three goals coming in the opening 20 minutes, with Alexis Sanchez scoring a brilliant brace.
With Arsenal picking up all three points, they're now level on points with their Manchester rivals, so Neville has made a bet with TV loudmouth and everyone least favourite Gunners fan, Piers Morgan.
Though we're sure both will end up donating to both charity's anyway, we do wonder who will actually win the bet. And we'll honest, we reckon Neville might just win but only if Wayne Rooney decides to return from his holiday he's seemingly been on since February.
