Celtic have done remarkably well on the pitch in the last two seasons, making history in winning back-to-back domestic trebles, a feat unprecedented in Scottish football.
They have also done very well off the pitch as well, keeping the core of the team that won all those trophies together.
That is set to change though, as Stuart Armstrong is reportedly set to leave the Hoops to join Southampton in a deal worth £7milllion.
In a way, it is remarkable that Armstrong is set to be the first major player to leave the team that has made Scottish football history.
It could be argued that the reason the 26-year-old is being sold is down to his contract expiring next season, otherwise the Hoops would no doubt have hoped to kept him at the club.
Peter Lawwell and Brendan Rodgers deserve great credit in not selling any players off last summer, such as Moussa Dembele, who has been speculated about for almost 18 months.
The test Rodgers and Lawwell face now is making sure that no other big name players depart the Hoops over the next 12 months, and with their contracts running out, there has to be a doubt over the Hoops futures of the likes of Dedryck Boyata and Dembele.
Continuity is key for this Hoops side in the last few years, which is why the departures this summer should be kept to a minimum.
