Shane Duffy arrived in Glasgow on Monday night and is in line for his debut against Ross County on Saturday.
The Irishman finally sealed his dream move to Parkhead on a season-long loan from Brighton.
The new signing will be paraded by Celtic later this week after his move was confirmed while he was on international duty with the Republic of Ireland.
But will Neil Lennon throw Duffy straight into the starting XI for the trip to Dingwall?
Including him in the line-up is one decision, but how the Celtic boss will set up his side if he does start the centre-half, is another.

Duffy could take Kris Ajer's place with four at the back or Lennon could deploy him in his favoured 3-5-2 system alongside Ajer and Christopher Jullien.
Do you think Duffy should start on Saturday and, if so, what formation should be used? Should Odsonne Edouard return to the side after his recent spell on the sidelines?
Or do you think Celtic should stick with the team that beat Motherwell 3-0 before the break?
