Did Celtic make a mistake by not targeting Aberdeen left back Graeme Shinnie?

Graeme Shinnie has been called up to the Scotland squad for the first time.

Scotland have announced their squad to face Poland and Gibraltar in their final Euro 2016 qualifying matches - and one name stands out.

Whilst Blackburn's Jordan Rhodes and Wolves midfielder Kevin McDonald are in the squad, Aberdeen left back Graeme Shinnie handed his first ever call-up to the Scotland side.

The 24-year-old defender, who joined the Dons from Inverness over the summer, has had a superb start to the season under Derek McInnes, and his performances have been rewarded with a place in Gordon Strachan's 27-man squad.

Shinnie's move to Aberdeen was on a free transfer after his Inverness contract had expired, and many Celtic fans will be wondering why the didn't make a move for the player.

Long-term Bhoys left back Emilio Izaguirre has been inconsistent at best in 2015, and manager Ronny Deila spent most of the summer searching for a player to come in and compete with the Honduran - or possibly even replace him at some stage.

Eventually, Manchester United's Tyler Blackett joined on loan, but even he is a centre back by trade who can fill in at left back if needed; not the competition fans had in mind heading in to the summer transfer window.

Yet with Shinnie, Celtic could have signed a consistent, attacking left back on a free transfer, giving Deila just what he needed on the left hand side of his defence.

It's unclear why Celtic chose not to sign Shinnie, but his international call-up comes at a time where Strachan has a number of left backs in the reckoning, such as Andrew Robertson, Lee Wallace and Craig Forsyth, illustrating just how highly-rated Shinnie is.

Given Celtic's recent transfer strategy of targeting Scottish players - after all, Gary Mackay-Steven, Stuart Armstrong, Scott Allan and Ryan Christie have all signed for the Bhos in 2015 - it would be little surprise to see them target Shinnie somewhere down the line.

Yet having had him in their lap on a free transfer, it currently looks like the Bhoys made a mistake by not pursuing Shinnie; and Deila's loss appears to be Aberdeen's gain, with the Dons lodging a serious title challenge this season, in which Shinnie is playing a huge part.
