An early penalty from Almen Abdi and a composed finish by Matej Vydra condemned Blues to consecutive defeats.
Both strikes came within the opening 20 minutes and Clark felt individual errors were contributing to their early deficits.
“When you go 2-0 down, it’s very tough to come back. We found that out Tuesday night after being in the same position,” assessed Clark.
“It doesn’t help when you consider the four first-half goals we’ve let in [against Sheffield Wednesday and Watford] are down to poor errors on our part. Individual errors where people aren’t doing their job properly. The penalty doesn’t even happen if we deal with it just over the halfway line and put it out of play. We’re not giving ourselves a basis to go play football on – we’re chasing the game.”
“It’s happened on two or three occasions now this season where the first half performances haven’t been good enough and we’ve given ourselves mountains to climb. On one occasion, we nearly did it; but today we didn’t get halfway up the mountain. We put their back four and keeper under a bit more pressure in the second half, but I can’t remember too many saves for Almunia to make.”
The hosts were imperious in the opening period and Clark felt that although Gianfranco Zola’s men were the better side, Blues helped them to be.
“In every facet of the game Watford were superior and I wouldn’t dare take away from their performance but we contributed massively to our own downfall. We’ve given away two very poor goals and it was very poor in general in the first half.”
Blues travel to Coventry this week in the Capital One Cup and Clark is looking for a reaction from his players in both an individual and group sense.
“But it’s a tough one because I know there is so much more in that dressing room. We’ve all got to respond, and all got to bounce back and start winning football matches and find a way to do so.”
“They’re great players and great lads who aren’t performing for one reason or another and you can get your point across without ranting and raving and shouting at them.”
“We’ve all got to take collective responsibility – that’s for sure.”
