I think we've both watched a fair few u23 games this season, if I remember the threads correctly. Yes, that goal by Ferguson against Everton was superb!, and he certainly looks good, for the future.
He hasn't been starting every single game though in the U23's even tbf, and it's a huge step up to Premier League level.
Where I would agree with you, is that if Locadia is the only alternative, then yes, it's got to be worth giving the youngsters some first team game time, in the absence of anyone else, all the time Welbeck is injured.
I think someone has already mentioned. Maybe it's devilment in such speculation? but I also wonder if bringing Locadia on is actually Potter sending out a message?
Yes, I agree, it would obviously be a gamble. The thing that makes me think Ferguson coud just be able to step up, apart from his obvious skills, is the way that defenders frequently just bounce off him.
Tolaj has also been mentioned - he was looking good earlier, but he's had some very quiet games of late.
Either of them, though, if the alternative is Locadia ..................................
