Willie Miller: Derek McInnes must act to make sure that second-half form is not repeated against Celtic

Tempers become frayed at Easter Road.

There are big questions marks over Aberdeen’s character going into Sundays’s league match with Celtic after being over-run at Easter Road.​

However, I believe the Dons squad is strong enough and manager Derek McInnes good enough to do that and show everyone the display at Hibs was a one off.

They were totally dominated in the second half in a a concerning performance as the fight just wasn’t there from the Dons after the break.

It will give Aberdeen a lot to think about with the game against the league leaders at Pittodrie fast approaching.

Aberdeen will know, unless they improve dramatically on that second half shift in Edinburgh, it could be an easy ride for the Hoops.

Mentally, the Dons will have to show they are up to the challenge to win back some pride against Celtic.

Aberdeen do not normally perform as poorly as they did after the break at Easter Road so hopefully it is an isolated incident.

The Easter Road defeat is a blow as it let Hibs right back into the mix as they are now just five points behind.

There was not much in the first 45 minutes in Edinburgh although Neil Lennon’s side slightly edged it.

When you come out after half-time you have to be fully concentrated at the back but Aberdeen let their guard down.

Within two minutes of the restart they were a goal behind and I expected a response.

It never came.

Instead it got progressively worse for Aberdeen and it could have ended up an embarrassing scoreline.

Jamie MacLaren could have had a hat-trick with the chances that fell to him but fortunately for the Dons he didn’t have the composure to finish.

The leadership and snarling personality of suspended skipper Graeme Shinnie was badly missed in midfield.

The Hibs midfield of Scott Allan, Dylan McGeouch and John McGinn were absolutely fabulous and dominated in that second half.

On loan Manchester City midfielder Chidi Nwakali came in for Shinnie and did fine in the first half and showed strength and nice touches.

He obviously knows how to play in that position but there is no doubt Shinnie’s absence was felt.

There was little separating the midfields in the first half but after that the Dons became disjointed. The team’s composure, organisation, discipline and shape went.

It is a concern Shinnie and Ryan Christie are unavailable for the game against Celtic. However, the manager has a big squad to choose from so it is something they should be able to cope with on Sunday.
