This article forms part of our The Ones That Got Away feature series, which is where Football Transfer Tavern take a look back at players linked with moves in the past, and see how they would have made an impact had they signed for the interested side.
Celtic have a history of signing the best players from other clubs in the top flight of Scottish football.
There are plenty of recent examples of this. In 2010 they signed Charlie Mulgrew from Aberdeen (The Guardian), who was labelled as one of the best players in the SPL at that time by Neil Lennon.
Then in 2015 they signed both Stuart Armstrong and Gary Mackay-Steven from Dundee United (BBC Sport) and they continued the theme in the summer just gone when they brought in Greg Taylor from Kilmarnock (Sky Sports).
Another top player they tried to sign from a fellow Scottish club was John McGinn, who at the time was plying his trade for Hibernian.
The Bhoys tracked the midfielder for the majority of the summer transfer window in 2018, and had three bids for him rejected by Hibs (Edinburgh Evening News).
McGinn is a boyhood Celtic fan and he admitted on Sky Sports that he had his “heart set” on joining the Glasgow giants.
But the move never materialised, and later that transfer window he ended up moving to Aston Villa for £2.7 million (The Times).
He has done extremely well in his time at Villa Park, and was a key member of their team as they won promotion from the Championship last season. Indeed he made 48 appearances in all competitions, scoring nine goals and providing 12 assists (via Transfermarkt).
Now he finds himself as a Premier League player, and he has made an incredibly impressive start in the English top flight scoring three times in nine appearances so far (Transfermarkt).
His performances have been attracting admiring glances from Manchester United (via Express) and his value is certainly now more than the £2.7 million Villa paid.
Celtic must be watching him flourish in the Premier League and wonder what might have been had they made an acceptable offer to Hibernian just over a year ago.
