The pair are both in the squad for this afternoon’s encounter with the U’s – managed by former Blades defender Chris Wilder – with boss Wilson eyeing more business.
He said: “I am delighted to have brought in players of the quality of Jamie and Danny. But I still want more signings this month and we have got irons in the fire. I am always on the look-out for players who can provide the goals that win you promotion.”
On the signing of pacy goalscoring Motherwell winger Murphy for £100,000 – which saw the Blades overcome interest from the likes of Rangers, Hull City and Huddersfield Town – Wilson added: “It is very satisfying to have got him because he was courted by clubs in higher divisions than the one we are in at the moment. But we are a big club, and I don’t see any reason why Jamie cannot fulfil all his ambitions here.
“Being in such good form will make it easier for him to settle in.”
Wilson, whose side have been beaten just twice in 90 minutes away from home this term, admits Wilder’s League Two outfit, who have reached the third round for the first time in 10 years, will represent a tough hurdle to overcome at the Kassam Stadium and expects them to be fully fired up.
The U’s are unbeaten in their last 10 games in all competitions and have won their last four matches.
Wilson said: “Oxford is a potential banana skin because they are on a good run at the moment. They have hit a rich vein of form and Chris Wilder, with his Sheffield United background, will have them well up for this one.
“I think Oxford are good enough to be up there in and around the play-off places at the end of the season, and they will be going into this tie in a confident frame of mind.
“They are a team who keep it tight at the back, can create through their wide players in midfield, and they score goals.
“Oxford is a hard place to go anyway, but we shall go there with a strong and positive attitude.”
The hosts will be without the suspended Jake Constable while midfielders Lee Cox and Jake Forster-Caskey have returned to their parent clubs.
