The Leeds owner was full of praise for the winger over the weekend.
The Italian was present to watch the clash and was full of jokes and laughter after the game, seeming far more relaxed than usual at Elland Road.
And, according to the Yorkshire Evening Post, Cellino singled two players out for praise after the game. One, rather unsurprisingly, was new signing Stuart Dallas - he's spent money on him, so why not encourage him - and the other was Sam Byram. The Byram reference could be very good news for Leeds.
Indeed, it looks as though the Leeds side will be built around the 21-year-old - among others, of course - and, even if interest in Byram increases this season, the fact Cellino has been personally impressed after watching him makes him even likelier to say no to any bids.
The praise for Byram's ability out wide also adds to the sense he will no longer be a Leeds right-back, although that has seemed clear for a while now.
It's rare Cellino singles out any Leeds players in particular after a performance, unless it's to criticise them, and his mentions of Dallas and Byram will no doubt encourage them both. The fonder the owner grows of seeing the 21-year-old's quality, in particular, the better for all at United.
