Realistically, they won't get regular game time. Pereira has too many players infront of them and Mensah hasn't even got a firm position yet.
Loaning them out is a great move. Likewise Borthwick-Jackson. They'll get proper football at good clubs (ideally) instead of pissing around in England's pathetic excuse of an U21 set up.
Not loaning players out soon enough has been one of my biggest issues with the club over the past few years. We had players like Tom Thorpe that were almost 22 and had barely notched up 20 professional games of football. We can't let that happen to this next crop.
You say they have got too many players ahead of them but surely there is a way around this. If you look at our midfield we have too many players that you just know can't take us forward so if we get Pogba, we should look at offloading Fellaini and Schweinsteiger to create space in terms of wages and squad options. That would leave us with Pogba, Carrick, Schneiderlin and Herrera as our four midfielders for two positions meaning TFM and Pereira can take the two squad roles as third back ups.
With the Europa and the CoC we have enough games to blood them in if the manager really wanted to. Not playing Pogba has turned out to be a hundred million pound mistake, lets not repeat it whilst in the midst of rectifying the first one. These kids have the talent to grow into world class players - of the kind the biggest clubs need and pay huge sums for - whilst the likes of Herrera, Fellaini and Schneiderlin are journeymen types and Bastien and Carrick are on the way out.
