Rangers signed up Gareth McAuley on a free transfer on Monday.
In doing so, it gives Rangers boss Steven Gerrard four quality centre-backs, having already signed Joe Worrall on loan to compete with first-choice duo Nikola Katic and Connor Goldson.
The Gers are in the Europa League proper now and nobody would begrudge them another centre-back, because they'll have a lot of games this season.
But did they sign the right one?
McAuley is heavily experienced, but the Northern Ireland international also turns 39 in December.
He was free so it's a low-risk signing as far as finances go, but the same could be said for Steven Caulker.
The former England international triggered a clause in his contract to leave Dundee shortly after the transfer window closed, meaning that he too is available on a free transfer.
Caulker is only 26 and still has plenty to offer any club - and he won't be long getting snapped up.
As decent as McAuley is, that's all he is - decent. Caulker has proven that he can be an excellent centre-back and if the Celtic-linked defender winds up impressing at Parkhead, Gerrard only has himself to blame.
