I’d be happy enough with him staying on. Done a good job so far off the bench and the experience / consistency would be a good option for a year.
as an aside. I think we should be making a play for the Phoenix keeper Alex Paulsen. Very young and has been our number 1 all season. 11 shut outs, 80% save rate, commands his box really well and can deal with crosses. Good with his feet too. Would be cheap and definitely better than Roos. He’s got a great future ahead of him and a move to Scotland would help him on his way.
