While the game is quite 1 sided, it is worth noting we are missing a number of the best under 18's. Mills, Price,Welch, Kouyate, Jagne, Onyango & Campbell are all fairly regular under 23 players (which is a good thing). Most of the players today are either 1st year players, and I think we actually have 3 or 4 under 16's playing. So we do just look smaller than Liverpool's players, who are older (which at that age makes a big difference).
They also recruit heavily at that age. I could be wrong, but I don't think a single outfield player has been brought in from us, but they will have 4 or 5 lads who have been expensively (the number 4 looks good).
At a more equal level (the 16's) we recently defeated them quite heavily. But a mixture of pushing a lot of players up, and perhaps not the investment into the 18's team due to a ban leads it to be more 1 sided.
