I think he was there for the press tour and staged an open workout. I didn't know he was still training there, I guess he wants his name to be bigger in the UK to help sell the PPV, if it's on PPV in the UK.
I think he's trying to pick up all of Ricky's old fans (assuming Ricky Hatton is done fighting). Lol at his pitch: "Manny hurt Ricky more than I did. I let him go 10 rounds. Come over to my side."
