I'd totally take him out of the limelight. Announce the signing on the club website, do the video with him talking up reasons why he wants to be here, not why he wanted to leave Liverpool.
Then give the press fuck all. They'll be waiting to slaughter him at first opportunity so why give them the chance.
Still remember that first Mancini press conference where they were baying for blood. Will be the same here.
Let him do the talking on the pitch, maybe Ward can give John Cross an exclusive a few months down the track.
