Republic of Ireland manager Mick McCarthy has confirmed both Callum Robinson and David McGoldrick have returned to the Blades for treatment on injuries.

McGoldrick scored in the 1-1 draw against Switzerland on Thursday but the Irish head coach revealed he had been carrying an injury heading into the European Championship qualifier:

“David came into camp with a shoulder injury but was determined to play against Switzerland and what a game he had. He was brilliant from start to finish and capped off a great performance with a first senior international goal that was no more than he deserved.”

Robinson also started the game but had to be substituted in the second half due to a hamstring problem:

“Callum felt his hamstring in the second half of the game so it is best now that he also goes back to Sheffield United for treatment.”

Manager Chris Wilder may not be too happy with Ireland’s treatment of Robinson, in particular. The 24-year-old did not train on Wednesday last week following concerns of a potential thigh problem, and it appears he aggravated the injury when he played against Switzerland.

The Blades face Southampton on Saturday afternoon, and both McGoldrick and Robinson are now major doubts for the game at Bramall Lane. If they do miss out, Oli McBurnie, Billy Sharp and Lys Mousset are the three contenders to start up front against the Saints.
