Oxford United's Argentine coaching team accused chairman Firoz Kassam of lacking ambition for the football club after they resigned yesterday.

Head coach Horacio Rodriguez and fitness coach Pablo Fernandez delivered a parting shot to the club's owner, who is looking for another new manager following Ramon Diaz's departure earlier this week.

And Rodriguez admitted he feared for Oxford United's future.

"I don't know about the future for them," he said. "Some people, they don't know anything about football; they know a lot of trades and gimmicks, but they don't know about football.

"The chairman here doesn't show that he has any ambition for the team to succeed."

Yet Rodriguez, who has been in charge of playing affairs since December, believed the coaching team were on the right track and could have got a promotion side together next season.

Kassam had suggested that just the two main coaches, Rodriguez and Fernandez, remained, but when they realised what was on the table, they walked away.

Originally it was a team of seven, but by the end Oxford didn't even want a translator around.

"Unfortunately, the offer to continue was for two people only - the physical coach and me," Rodriguez explained.
