DEREK MCINNES admits Aberdeen got what they deserved as they crashed to a 3-0 defeat at Ibrox.

The Dons missed the chance to extend their advantage over Rangers in the Premiership standings as a James Tavernier double, the first from the spot, and Carlos Pena strike clinched a comfortable win for Graeme Murty’s side.

A late red card for Ryan Christie added to McInnes’ woes as he turns his attentions to the rematch at Pittodrie on Sunday afternoon.

And the Reds boss was disappointed with a poor performance as his side failed to fire against an under-pressure Light Blues outfit.

McInnes said: “It was a sore one. We got what we deserved.

“We spoke about quietening the crowd at the start of the game, put pressure onto the Rangers players after the couple of results they’ve had, but we gave them the complete opposite, we gave them a life.

“It was a needless penalty to give away. We need to show more restraint there and awareness. It helped get their crowd into it.

“I thought the Rangers players were brighter than us, showed more energy than us in the middle of the park. They won more headers, they were more aggressive – everything I expected from my own team to be honest.

“We get to half-time 2-0 down and I did think there was still a result there for us, if we could get the next goal and go on and win the second half. I thought we were far better, in terms of personally the shape was better and we took on more responsibility.

“People might say that it doesn’t matter if it’s 2-0 or 3-0- but it’s such a poor decision by the linesman because he (Tavernier) is a couple of yards offside when he puts the ball in the net. These linesmen should be accountable for these decisions.

“Losing 3-0 doesn’t matter in terms of the points but I thought it was harsh to lose the second-half.

“Ryan got himself sent off, foolishly, so it wasn’t the greatest evenings for us. We just need to dust ourselves down, look for a reverse on Sunday and the right result for us.”
