You'd probably have said the same about Beckham, Giggs, Scholes and Neville in 1992
Yes but only Giggs was playing in 1992.
Beckham was still to go on loan to PNE etc

If a new manager gives them more game time then fair enough but Dowell isn’t playing every week in the Championship so it’s a stretch to think he’d get suitable minutes here next season when Sigurdsson is pretty much the same player but with better off the ball attributes.
A lot will depend on whether we have a systems manager (ie someone who prioritises how theY want to play over what players they have available) or not, as they are more likely to pick a youngster as they may not have a suitable experienced player available.
