I think young Welsh deserves another chance. He will have learned a lot from that game against St Mirren, mainly dont expect a Scottish Ref to award a blatant foul against you in the box. Expect the unexpected, be more aggressive, let these cloggers know he can kick back too, guys like Main will take advantage of any young player so hopefully its a lesson well learned.
At the other end we have been very wasteful too. Far too many chances have gone begging lately, especially in Europe, Kyogo, GG, Maeda, even Jota and Abada, all seem to have lost their shooting boots, or got them on the wrong feet. These next few games are crucial for confidence.
Time for some grit and graft.
