Oxford United should not get carried away after a promising pre-season, says newboy Jon-Paul Pittman.
The U's completed an unbeaten summer build-up with a 1-1 draw against Thame United on Monday.
The striker, 24, told BBC Oxford: "We should just be quiet and not shout from the rooftops. We need to go on with our jobs quietly.
"Maybe come Christmas time people will look at us and say they are doing well but we've done nothing yet."
United finished last season five points outside the play-off places in 12th.
They open their campaign away at Rotherham on Saturday.
