Oxford United manager Michael Appleton believes his side are more than capable of matching Premier League opponents Middlesbrough in the FA Cup fifth round.
The League One side have already knocked out Championship sides Rotherham United and Newcastle United on their way to the last 16.
Oxford will bid to reach the quarter-finals of the competition for the first time since 1964.
"The prize is massive to try and get through," Appleton told BBC South Today. "We know how difficult the task is going to be."
