Bristol Rovers boss Mark McGhee claimed his side were denied a blatant early penalty as they were held to a 0-0 draw by Oxford.
McGhee was incensed referee Phil Gibbs only gave a corner when Danny Woodards was sent flying by Oxford goalkeeper Ryan Clarke after a mazy run in Saturday's League Two clash at the Memorial Stadium.
The officials clearly felt Clarke got a touch on the ball and Woodards was heading away from goal but McGhee said: "I thought it was a stonewall penalty at the time and that has been confirmed by film of the incident.
"But overall I consider this a positive result and performance. I felt our goalkeeper and back four performed very well on a difficult surface and the players in front of them put in good shifts too.
"The clean sheet shows we are becoming difficult to beat and if we stay tight at the back there is always a chance we will score.
"I am taking the opportunity to look at different combinations of players as well as at individuals. Both teams showed a good attitude. Oxford are a decent team and it was a closely contested match."
