The City youngster has found himself pushed along the Eastlands pecking order following the club's recent signings and is now set for a move to Sheffield for a fee of around £3m.
The Blades have chased the young striker all summer and having pocketed £10m from the sales of Kyle Naughton and Kyle Walker to Spurs, the Sheffield club upped their offer after a £1.5m bid was rejected earlier in the transfer window.
City continue to clear the ranks after offloading Ecuados striker Felipe Caicedo to Sporting Lisbon for a season long loan, the Portuguese club announced this afternoon.
The club are yet to confirm both deals.
