Van Dijk was shown two yellow cards in the first half of the game and feels he was hard done by through poor decisions from the referee.
“I got a red card and I feel horrible. I need to learn from it. It's going to be tough. The referee was horrible,” said van Dijk.
“Now you're the worst player Celtic have, that's what they're going to say right now, but another day, you'll be the best player. That's an awful feeling.”
Van Dijk’s dismissal meant it was always going to be difficult to compete during the game with ten men but they fought admirably.
They kept going and only conceded with a few minutes left to go in the game and that fighting spirit is something that will benefit them over the coming weeks.
Where manager Ronny Deila has to act quickly and sensibly is ensuring that van Dijk isn’t too affected by the feelings he mentions which were created by the sending off.
He’s clearly wary of the way he’ll be perceived for getting sent off last night, but the referee appears to be the one at blame and not the Dutchman.
Van Dijk will likely be very determined to react in the right manner this weekend in the important league game against Aberdeen, which represents a chance for the team to extend their lead at the top of the Scottish Premiership.
He will be a crucial figure for the team over the rest of the season and fingers crossed he won’t be penalised as harshly by any other referee over the rest of the season.
