Burton boss Paul Peschisolido felt his side`s 1-0 FA Cup win against Oxford was "well deserved" and was full of praise for matchwinner Aaron Webster.
Despite nursing a calf strain, striker Webster came off the bench to head the only goal of the game in the 85th minute and set up a tie against League Two leaders Chesterfield.
Peschisolido said: "I told the lads a goal would come if they stayed patient. We had the lion's share of possession in the first half, we pinned them in their half of the pitch and we had numerous situations where we should have scored.
"But we kept plugging away and in the end we got the goal we deserved. It was a great goal from a great cross. Aaron (Webster) has been coming up with the goods this season and, to be fair, it was (assistant manager) Gary Rowett who suggested to me to get him on.
"We needed to get some balls in the box and we needed someone like Aaron, the best header of the ball at the club, on the end of it.
"He's always an aerial threat and I'm delighted he got the goal that put us in the next round. He attacks the ball ever so well."
