"But I feel for Boro. I didn't want to play Middlesbrough, to be fair, because do you celebrate - yes or no?
"I'm a little bit disappointed for them, I wish them all the best and the fans were magnificent. But at the end of the day Cardiff pay my wages and I have to try and do my best for them and you are in a game to win."
Despite the crushing manner of their defeat, Hasselbaink is tipping Boro to rebound.
He added: "Gareth (Southgate) is doing a good job here and I hope they bounce back.
"They have got five difficult matches coming up, but I don't think they are in relegation danger."
