The club has bought up 3 or 4 of the best RB prospects in the world so I think we'll be OK when the time comes. Pedro Porro, €20m buyback announced yesterday (€40m for other clubs) might well be Spain's starting RB at the Qatar world cup. We've got the Brazilian kid, Couto, we've got Issa Kaboré playing at Troyes. CJ Egan Riley is a decent academy prospect, Sam Robinson captains the u18's. Jeremy Frimpong would probably jump at the chance to come back, he's apparently pulling up trees in Germany.
Or most likely - we'll just buy one. Livramento, Lamptey, Rencsh at Ajax looks good. There's a lot of options.
