Celtic have witnessed some huge success in the transfer market since Ange Postecoglou touched down at Parkhead, bringing in a colossal 14 new faces.
What the vast majority of those acquisitions have done is sensational, with the Hoops now in the running to win the treble.
Postecoglou's men have won the Scottish League Cup, now hold the advantage in the title race and face their biggest rivals in the Scottish Cup semi-finals next weekend.
However, there have been some blunders, as there is with every team.
Ivan Toney is a classic case of one that got away but there are plenty of other players who the Bhoys will rue not signing.
Take Brenden Aaronson for instance, someone whose stock has risen quite considerably since Celtic were interested in acquiring him.
Back in 2020, he was linked quite regularly with the Hoops but a move didn't materialise and that's something they should now regret.
Of course, in the context of how Celtic have done this term it's not mattered. Yet, had Aaronson joined last season it's unlikely they'd have witnessed such a dismal year.
Instead, he signed for RB Salzburg in January 2021 in a deal worth £4.6m and he has gone from strength to strength since.
The attacking midfielder has totalled ten assists and five goals throughout the current term and has earned considerable praise as a result.
He was dubbed "special" by his manager, Matthias Jaissle, and also hailed as a "mentality monster."
That acclaim has now seen calls for a Premier League move with Leeds United's interest in the American incredibly well documented.
They wanted to sign him in January and still hold interest ahead of a summer move but with Transfermarkt rating him at £18m, any chance of Celtic finally bringing him to Scotland is now impossible.
Ranking in the top 11% of players across Europe for goal-creating actions per 90 minutes and in the top 1% for pressures, it's evident just how well the 21-year-old would have fitted into Postecoglou's ranks.
It's a shame they didn't sign him but in Tom Rogic, David Turnbull and Matt O'Riley, the Hoops certainly have reason to be happy about their options.
