Potential further back than Cleverly ......thats completely pointless, apart from putting MORE games at risk from lack of experience, and the younger player not as easily able to learn from Cleverly (as Cleverly would be able to glean a lot more from a much more experienced player)
I wasnt knocking the guy at all - I think he was a great prospect for the future but imo would be a lot of pressure on the young lad to put him in such a prominant position 1st season playing for Utd
Re Barca game - while I noted you didnt watch, Iniesta, Xavi and Messi didnt play so it was a pretty mix and match side that Utd beat last week
Not sure what the problem is, you seem to be basing Cleverley's current level on his age, there are plenty of 25 year olds that are MUCH worse than Cleverley is now, you don't have to learn from an old player to gain anything.
There aren't many central midfielders in the world of any age who couldn't watch an 18 year old Cesc to get tips on how to improve.
Buying Sneijder won't make certain you beat Barcelona, infact I'd say it was still almost completely as unlikely, even more so if you play the same way as last time, going for a defensive fluke and playing into Barca's strengths.
In Cleverley's case, or Wilshires, or Cesc's, you could have gone on about their age, bought a 30mil midfielder in and benched those players, or push them into the first team, and get a player better than the 30mil guy you would have brought in. His age is irrelevant, he's actually very good now, he has potential to be better but we're not talking about he's like Obertan now, with the potential to be better than Scholes, he's above average in his position in the EPL< maybe way above average, with potential to be better than Scholes.
Every game you bench him for, is frankly a game further away from being the actual best option you could have for that position.
For me, from what I've seen today, and in preseason and at Wigan you're talking about being at a similar level to Wilshire, the point where playing him is best for him, and the team and bringing in a player who will automatically play ahead of him will hurt him more than help him.
He will learn a heck of a lot more playing games and getting up to speed, than training with a more experienced player, and getting few if any games.
The Barca preseason game meant nothing, as you said, I'd say 6 players started who wouldn't normally start games for them OR wouldn't have played in the same position. Though Thiago could well replace someone this year as first team.
