I dont disagree but unless you think Martinez has some personal motives behind it, I dont see what you're getting at. Yes, we were hoping for a better loan spell, so was Henriques. It didnt happen, there could be plenty of reasons behind it. Maybe Martinez just doesnt see it in training and lets face it, giving a United player gametime isnt really on his priority list. Maybe he wanted someone of his own squad who doesnt feature much to get minutes or maybe he just wanted continuity and hence didnt bring Henriques on.Let's assume he isn't better than what they have, but still they have had plenty of chances in games won already or games lost to give him even 20 minutes. In a couple of games there were unused sub's too but he wasn't even brought on against a league 1 team while leading by 3 goals or in the other game leading by a couple of goals and opposition 1 man down.
There's a huge plethora of options between being first name on team sheet and being a completely blanked out bench warmer getting 0 minutes and not playing U21's either.
