Swansea City interim manager Alan Curtis was disappointed with his team, but full of praise for Oxford United, after they were dumped out of the FA Cup with a 3-2 defeat on Sunday.
Jefferson Montero put the Swans ahead at The Kassam Stadium, but the League Two side hit back through Liam Sercombe's penalty on the stroke of half time and a brace from Kemar Roofe after the break.
The Welsh side had made 10 changes to the team for the match, and pulled one back through Bafetimbi Gomis in the 66th minute, but Curtis labelled the defeat as "hugely disappointing for ourselves".
"All credit must go to Oxford, I thought they were excellent today," he said. "They were much more energetic, they passed the ball and were the better side overall.
"The only time we looked like a team was when we went 3-1 down – only then did we start to play but it was too late then,We made a lot of changes today with Wednesday's game against Sunderland in mind but we made similar changes over the Christmas period against Palace and produced a battling performance there but we did not repeat that today.
"We fielded players with lots of Premier League and international experience. The team we fielded was good enough but did not produce a result, which is hugely disappointing. It is disappointing to be out of the cup at this stage because it gave us an excellent opportunity for more players to get game time."
With the Swans now out of the FA Cup they can turn their full attention to the Premier League, where they sit 17th in the standings, just one place and two points above the relegation zone, and face another relegation-threatened team in midweek.
"We must now turn our attention to Wednesday's game at home to Sunderland, which is massive for us," Curtis added. "We won't let this result affect our confidence heading into that game. We must look to put the disappointment of the cup defeat behind us, dust ourselves down and move on."
