BBC Radio 5 live sports extra
Former Southampton striker Kevin Phillips on BBC Radio 5 live sports extra: "I think this is a great time for Sheffield United to be playing Southampton, they have had a bit of sticky form recently but Ronald Koeman is taking this competition very seriously and you can see that from the side he has put out.
"However, Nigel Clough's side have shown they can perform when it matters and they can certainly get a result tonight."
