Walter Mazzarri admits his anger at referee Bobby Madley's performance resulted in him forgetting to shake Mark Hughes' hand after their defeat at Vicarage Road.

Watford were well below par during this afternoon's 1-0 loss to Stoke City. Miguel Britos was sent off late on and the visitors' winner was fortunate after Charlie Adam fouled Valon Behrami in the build-up to the goal.

Mazzarri's anger at the final whistle distracted him but the Italian later shaked Hughes' hand in the dressing room.

The Hornets head coach said: “I was very angry at that moment with the referee and the extra time that he gave at the end of the game. But of course then you can ask Mark Hughes.

"I went in the dressing room and gave him my hand. I forgot in that moment [full time] and didn’t think about it but I was angry with the referee. You cannot give only four minutes of extra time after all that happened in the game and the decisions he took during the match."

Mazzarri added: “You have to look at the whole game and the distribution of yellow cards, the fouls and even the goal they scored.

"You have to look at the whole 95 minutes and the distribution of the yellow cards was much more towards us. But it can happen for anyone to have a bad day and on this occasion I think he [Madley] had a bad day."

Stoke boss Hughes said: "Yes I am a little disappointed. It is something maybe the foreign managers don’t always do and they need reminding it is something we do over here.

"Mind you, British managers are in a minority these days so maybe we shouldn’t expect it. It was an emotional game and I think he was a bit emotional afterwards.

"He needed to be reminded and I’ve shaken hands with him since. I think he needed to be told he should have done it, so that’s fair enough."
