The formalities have been completed on Ollie Norwood's permanent switch from Brighton & Hove Albion.

The Blades have paid the Seagulls an undisclosed fee for the Northern Ireland international who has impressed since arriving on-loan at Bramall Lane in August.

Norwood has been instrumental in United's climb to third place in the Sky Bet Championship, with the 27-year-old scoring twice in 24 appearances in all competitions for the Blades to date.

Meanwhile, it can also now be confirmed that both Ryan Leonard and Lee Evans have made their loans to Millwall and Wigan Athletic respectively into permanent transfers.
