DUNDEE United manager Ray McKinnon admits a change of formation at half-time led to his side coming from behind to take a slender 2-1 lead into Friday’s Premiership play-off second leg at Tannadice.

McKinnon’s men were poor in the first 45 against Morton but the change from 4-2-3-1 to 4-4-2 allowed the Tangerines to create more chances, with the decision to move Simon Murray from left-wing to a secondary striker paying dividends in the end — after the forward bagged the equaliser to begin turning the game on its head.

The Tannadice gaffer reckons his troops were good value for their victory, despite Morton’s dominance in the first half.

McKinnon said: “We made a change at half-time, we changed the system with Simon Murray out left because I didn’t think it was working. We didn’t have any real quality down the left-hand side because he was wasted there.

“Tony Andreu was getting man marked out the game, so we thought we’d pull Tony out of there and move Simon out and we got an instant response. Plus it gave us the opportunity to put a lot more pressure on their back four.

“I don’t think we were fortunate to win, these games are difficult, play-off games are hard.

“Morton were decent in the first half, they got that start but it was a great response from my players in the second half and I’ve been saying that for the last seven weeks.

“It’s a tough place to come, Morton, and I’m pleased that we’ve come away with a 2-1 win.

“The goals were different class but we’re taking nothing for granted. They’ve got a fantastic manager, a great talented squad of players and they’ll be a real threat on Friday, so we have to be really focused for that second game.”
