Martina was fine yesterday but I don't see why he should be playing ahead of Holgate. He's the better crosser but that's pretty much it. There's not much to choose between the two of them in terms of athleticism. Holgate has a better first touch, is more confident in possession, defends better 1 v. 1, and is more responsible positionally even though he isn't a natural right back. I don't think Martina's crossing is good enough to outweigh all of that, not to mention that we don't have the targets right now to consistently take advantage of deep crosses from our fullbacks.
Maybe the plan is to play Martina when we need to attack lesser opposition (like yesterday) and Holgate when we need to be more resolute defensively. That's fine, I guess, although I'd still feel more comfortable with Holgate on the pitch.
Seamus can't come back soon enough.
