Gibbs-White or Bruno Guimares are players with that engine and desire.
Neither of whom are likely to join us.
I suspect we will stick with Barkley and Luiz for CMF cover next season and look to Alysson and one of our youngsters to cover the right side of MF / attack - Burrowes, Broggio, Rowe and KY are all in the play-or-sell part of their career with us now.
The players we really need top-class medium-term replacements for are McGinn and Kamara, and they will probably need to be purchased.
Sorry but I completely disagree with the bold bit, and reinforcing this sort of thinking is probably the worst thing Purslow ever did. They are 18, 19, 19 and 20 respectively. Play-or-sell is really what you should be considering when they're hitting 22-23. In the meantime it's about giving them opportunities to grow, either by training with the seniors under Emery, getting a loan or being allowed to grow by taking on leadership roles in the U21s (as Burrowes has). We don't need to be in such a rush with these players so long as they're happy with how things are going.
