Goals either side of the break from Esmael Goncalves and Christophe Berra were enough for Hearts to see off a Dundee side who were missing the vital end product that has been absent all of this season and of last.
This result seen Dundee slip into the play-off position with a massive game looming this Saturday at Dens Park against bottom of the table Partick Thistle.
“I thought we were better in the second half for a wee spell,” said McCann.
“But I am not going to say that cheered me up any. That was a shocking performance tonight. I didn’t see it coming and it won’t be accepted.
“It is something we work on at this club, where everything is geared to winning.
“Everything we do in training has a purpose, everything we do has an end point where it is about standards but tonight’s performance was a joke.
“Anything in the second half would have been an improvement on the first.
“I am not accepting that. When you set standards you should stick to them and if you fall below them, something like that can creep in so I am not accepting that.
“I think you can take it from my tone that I am not happy with them (the players) and they know that.
“That’s not right. The fans who travelled down from Dundee have been short-changed.”
We caught up with Hearts Till We Die again to speak about their brand new Stand, how the Levein era is going so far and his predictions for Tuesdays game.
The last time we spoke, the new main stand at Tynecastle was under construction. It’s now up and running. How does the old lady look?
The new stand is looking fantastic, still work to be done inside but after that's all done, it'll look even better!
The opening hasn’t gone by without any controversy. There was the possibility the first game against Partick might not go ahead right up to the day it was due to take place. Then after being giving the go ahead to play the game was put back to 3.15 as there was a problem with the turnstiles. And then two fire alarms went off before the Hamilton game also pushing the kick off time to 3.15. Hopefully that’s the end of the teething problems?
Yeah those delays were pretty annoying but at the end of the day, 15 minutes isn't much. I'm sure there won't be anymore delays.
Since your return to Tynecastle, the team have three draws and one win. Have you been disappointed with that return or have these results been expected?
Yeah, I'm not going to sit here and lie. Results have been pretty poor but thankfully we finally got a win at the weekend to end our poor form. I’m just hope the winning continues.
Until your victory at the weekend, there was only a three point gap between yourselves and the play-off spot. I think you were also six games without a win. Did you start to have a wee glance over your shoulder?
To be honest, I haven't paid a lot of attention to the league. It’s still very tight to call. I, of course, have had the odd think of where we could actually finish but there's still a long way to go.
You described the appointment of Craig Levein as satisfying but you weren’t over the moon with it. What’s your feelings so far into his current reign?
Of course, results haven't went to plan and the style of play hasn't been very intriguing but I always stick by a manager. I'm very much rooting for Levein and hope he succeeds in his second spell.
We have already clashed this season with Dundee coming out on top with a last minute winner at Dens. Understandably I was happy with the result and thought we deserved the win. That was my verdict through my dark blue specs but what was yours through your maroon ones?
It was a very disappointing result, especially losing it in the last minute. But hopefully, we are the ones to come out on top this time around!
We end it as always with a score prediction. Hearts will be bouncing after their first win in six and first in front of the new Stand while Dundee have picked up a bit of form and were unlucky to not come away with at least a point on Friday against Aberdeen. How do you think this one will end?
I reckon it'll be a very tight game like our last four have been and I expect Dundee to make it hard for us but as long as we make use of big Laff, we should pip it. I'm going for a 1-0 Hearts - Lafferty the goalscorer.
Good Luck for tomorrow!
Despite the defeat, McCann has promised to not be too hard on the players as he was happy with the performance.
“We deserved to take something from the game,” said McCann.
“Their keeper Joe Lewis has made two very good saves and there was also a shout for a penalty.
“The boys deserved something for their application and the chances we created.
“The performance was there, although we didn’t get anything from the game.
‘The players have shown a lot of character to stay in the match.
“It shows respect that Aberdeen decided to camp in and hit on the counter-attack.
“Coming up against a team who have been the second best in the country for the past few years, though, I think the players can be pleased and I haven’t been too hard on them.
“I have told them there is no disappointment here because I was happy with the way they played.”
