Quique Sanchez Flores bemoaned Nordin Amrabat’s red card in the 3-1 defeat West Ham, while he also refused to commit his future to Watford.
The Hornets clearly had one eye on Sunday’s FA Cup semi-final against Crystal Palace with boss Quique Sanchez Flores making seven changes.
Yet they still got one back through Sebastian Prodl and had a late penalty of their own saved before Nordin Amrabat was sent off in injury time.
Amrabat saw his hopes of a Wembley appearance ended by a second booking for a foul on Winston Reid.
“A second yellow was too much,” moaned Hornets boss Sanchez. “It was normal, not enough to be a second yellow.
“We conceded two penalties again and the first goal we reacted too slowly to Carroll, so we have to analyse that.
“We planned to make a lot of changes but I think we were competitive and we created chances.”
Sanchez is also dealing with speculation surrounding his position amid reports Watford’s owners are not happy at their form since the turn of the year – they have won just three league matches in 2016.
The Spaniard added: “We have an amazing time now – we have 41 points, the position is very comfortable we are in semi-final of FA Cup. The future we will see what happens.”
