West Bromwich Albion boss Alan Irvine is delighted with what he's seen this week from Liam O'Brien.
The midfielder was not initially in the squad for their 3-2 Capital One cup win over Hull but was called on after Chris Baird pulled out through illness.
The 21-year-old discovered he was starting just hours before kick-off and played a major part in Albion's victory on Wednesday.
"Liam only found out he was playing on the afternoon of the game because Chris complained of feeling unwell," Irvine told the club's official site.
"I have to say I thought he was outstanding and showed us what he is really capable of doing.
"It was a superb exercise for us because we managed to get full games out of so many players who needed them.
"To get a performance and result like we did as well only adds to the satisfaction."
