It’s set to be a big summer of goalkeeping change at Celtic as Brendan Rodgers faces major decisions.
Joe Hart will call time on his stellar career in the game at the end of the season, leaving Celtic needing a new number one. That leaves Scott Bain as the likely senior option left come pre-season, as Benjamin Siegrist is also reported to be heading towards the exit.
Not only do they need a new starting man, Celtic are likely to be seeking another back-up to whoever comes in for the starting role. That could spark a rake through the bargain bin, with other areas of the team needing upgrades.
We have listed through the best of the stars currently out of contract at their current clubs, with a view to two possible vancies. From Liverpool and Newcastle men to a legend of the Champions League, there are all sorts of options for Celtic to consider around Europe.
Here are the best of the options as things stand.
