All about opinions. I think Skalak is a very good player with a bit of pace and a lot of skill as confirmed by his international status. He isn't tricky or really pacey, but he has a bit of edge about him and CH needs to get him back on his devastating dead ball deliveries rather than Knockaert.
Th edge might be his aggressiveness, which he had to curb as his foul count was OTT. I would have started Sidwell instead and I would have started Lualua (for Murphy) if he was not injured. Or even Baldock ahead of him, as he was playing on the right.
I donlt go for two inverted wingers. Sometimes, I don't even think playing two wingers is best at all.
