Steve McClaren has responded to the angry chants which punctuated Newcastle United's FA Cup defeat at Vicarage Road.
A 44th-minute goal from Troy Deeney condemned McClaren's side to a fourth successive 1-0 defeat and booked Watford a place in the competition's fourth round.
Newcastle had dominated the first half, but, yet again, they couldn't take their chances.
Deeney's goal came from a misplaced pass from Georginio Wijnaldum.
And United's 2,809-strong travelling support voiced their anger at the relegation-threatened club's predicament – and owner Mike Ashley – during the second half.
Supporters chanted "you're nothing special, we lose every week", "we're s***, and we're sick of it" and "we want our money back".
There was also a chant of "you're not fit to wear the shirt" aimed at substitute Florian Thauvin.
Head coach McClaren had made just one enforced change for the third-round tie.
Asked if he felt the chants were "harsh", McClaren said: "I thought very harsh.
"I think we've had two games – Leicester and Crystal Palace – where, yeah, we were all angry and frustrated and we could accept criticism.
"The attitude of the players, that's all they (the fans) ask – do they work, do they chase, do they win tackles, do they create chances?
"We've had 25 crosses. We've had 25 crosses in the game, they've gone across the keeper, (heurelho) Gomes has made saves, our keeper's not had a save to make, and you can't ask any more from the players.
"So we just have to get on with it.
"Unfortunately that's the nature of football. Players have to be big enough and bold enough, have courage, and we've talked about that.
"They're certainly having that. It's just not having luck at one end and not sticking the balls in the net.”
Newcastle return to Premier League action on Tuesday night when they host Manchester United at St James's Park.
The club is 18th in the division and two points adrift of safety.
