Another man for whom the Parkhead club picked up a significant transfer fee is left-back Kieran Tierney, who joined Premier League club Arsenal in August 2019 for £25m.
Prior to joining the north London club, Barry Ferguson claimed that a transfer fee of £50m for the full-back would have been cheap, highlighting just how highly the 24-year-old was rated during his days in Scotland.
Now that the summer transfer window is around the corner, this could give Ange Postecoglou the chance to sign his own version of Tierney and bring a new left-back to Celtic.
Back in December, the Parkhead club were linked with a move for Hibernian full-back Josh Doig, but they failed to secure his signature in the January transfer window.
With the summer in mind, this should give the Hoops an ideal period to reignite their interest in him and finally bring the 19-year-old to Glasgow.
Having played in 74 senior games for his current club, the teenager has scored one goal and provided six assists along the way.
In comparison to current Celtic left-back Greg Taylor, the Hibs youngster has shown just how capable he is of playing in the Premiership. This season has seen the 19-year-old record more crosses, interceptions and tackles than Taylor.
Even though the Hibs youngster has played 10 more games than the Celtic defender, he has still committed fewer fouls (12) than his fellow countryman (21). This shows that he may not be as much of a liability as Taylor, whilst still having the talent to be a defensive and attacking threat.
Hailed as a “phenomenal” player by Ray McKinnon, Doig could be an ideal long-term replacement for Tierney and be a major competitor for Taylor in the Hoops’ line-up.
Moving forward, if Postecoglou thinks that his defence needs some reinforcements during the summer, securing a deal for the Hibs talent should be at the top of their list.
