Along the way to beating former team-mate Barry Ferguson’s Ibrox benchmark, there have been 37 clean sheets with some shut-outs recorded against some of the more glamorous of European names.
Great saves stick out in the memory in both the Champions League and the Europa League and UEFA Cup before it throughout a European career that began way back in September 2006 and a trip to Norway.
