Walter Mazzarri has expressed his dismay after Watford were knocked out of the FA Cup at the hands of Millwall on Sunday, claiming that he is "disappointed, angry and sorry for our fans".

The Premier League club were beaten 1-0 at The Den through Steve Morison's volley five minutes from time, leaving the Hornets with just one win in their last nine matches in all competitions.

Mazzarri told Sky Sports News: "I will speak with the players face-to-face [on Monday]. We didn't deserve to lose. If the referee had given us a penalty in the second half [for a challenge on] Stefano Okaka it would have been a completely different game.

"I'm very disappointed, angry and sorry for our fans. It seemed we were never going to concede but we ended up conceding. A lot of players have been missing but slowly we're getting them back.

"This is also the reason we had to change [the team]. I want a team that in the next 16 games [until the season's end] fights for every ball."

Watford, semi-finalists last season, managed just one shot on target.
