Think the incident you was referring to was after Foster's second try and we was kicking off, to me he looked to be complaining to Sam whilst looking at the Screen rather than it being directed at a fan because Sam kept looking round and checking the screen

I saw he was having a moan at Deacon at the end after he[Deacon had kicked on the second tackle with 30 seconds to go

He did seem to be frustrated at points during the game
