The Martina one is ok with me.
I would really really really like to see Kenny start, but ok, from our league fixtures i can see why Koeman will go with Martina
A 20 year old full back with 2 premier league appearences to his name, playing city away, chelsea away, spurs home & utd away.
What happens if he has been torn apart by hazard, pedro, de bruyne, silva, silva & sterling in our first 2 away matches and his confidence is shot? Do you put him in against spurs? as you have no one else, Martina is an option to start or to be back up. As someone else mentioned, we could go and spend shed loads on a top class back up but surely that stunts Kenny's progression more?
My preference would be, start Keny for these europa league qualifiers and see how he gets on, if he looks the bizz start him for the season, if he dosent, pull him out for Martina or even Holgate.
By the way, while we all know that Holgate is in no way a right back, people are going abit over board about him not being able to fill in there, he may not get up the pitch like a natural full back would but he defends well in that position. That could be a good thing for the opening games as we are facing some of the better teams in the league
