Benjamin Siegrist could be good for Celtic.
But the biggest question for the Swiss if an opportunity arises must be whether Parkhead would be good for him.
Celtic is a massive institution. Just being part of it would be something special for any individual involved with the first-team squad.
Being involved on huge European nights, being part of groups who are winning trophies and collecting medals, it has its appeal.
But footballers always say that it’s about playing games. That it’s about getting out there and doing their stuff. That the biggest satisfaction comes from being able to perform on the biggest stages at the highest possible levels.
With Joe Hart having a firm grip of the gloves, that’s unlikely to happen for Siegrist at Celtic.
He has built a strong reputation during his spell at Dundee United with some of his performances out of the top drawer.
The stopper’s form has caught the attention of many suitors with Parkhead recruitment staff amongst those keeping a close eye on him in the past year.
After years of hard graft, Siegrist has now established himself as a No.1 keeper due to his terrific performances at Tannadice.
And that’s where any decision would become difficult because the role of back-up goalkeeper can be one very cold place. Just ask Vasilis Barkas.
It’s exit of the Greek to Utrecht in Holland which has opened a slot in Ange Postecoglou ’s squad for a new goalie.
But, crucially, Celtic aren’t chasing a No.1. They’ve got one in the shape of the outstanding Hart who has brought quality and calm to the Aussie’s ranks.
Hart has international and Champions League experience. Barring some bizarre turn of events, he’s going to be the first pick for the foreseeable future having signed a lengthy contract last summer, especially as Celtic are going back to Europe’s top table.
With many of the expected outfield unit inexperienced at that level, Hart is one cornerstone that you would imagine Postecoglou is going to lean upon.
Being a squad man is tough enough for an outfield player, but at least you can play different positions and rotation gives a better opportunity of some minutes.
But keepers are different. Managers don’t tend to like messing about with their No.1s. They like the continuity.
Perhaps one of the best comparisons when you look at the position and the clubs potentially involved Lukasz Zaluska.
Performing superbly for United, the Pole’s form earned him a transfer to Glasgow’s East End. At that time, Artur Boruc was the top pick and the assumption was he’d be slotting into the role to eventually take over as the main man.
It never happened. When the Boruc path blocking his road was removed, the even larger-sized block of Fraser Forster was parked in front of him.
When the Great Wall departed to Southampton for big money, Craig Gordon entered the building to keep Zaluska on the fringes.
Now everyone's different. Zaluska got his chances to play now and again during that period and seemed thoroughly content with life throughout his time at the club. You can understand it.
And, of course, every player believes in their ability. So Siegrist would believe he could eventually usurp Hart and become the No.1.
Injuries and suspension can happen. Chances can suddenly arrive for a keeper.
Look at David Marshall. One red card for Rab Douglas against Barcelona gave the teenager a chance to grab his chance in Nou Camp and a career was born.
For Celtic, it seems ideal. A ready-made and proven back-up for Hart on a free.
But, at the age of 30, Siegrist surely wants to be a first pick. And he’s going to have to be very careful about making sure he takes the right option whether it’s Celtic or anyone else.
