The boss was though, quick to point out that it was just a pre-season friendly, but feels that the confidence level of his new recruit will benefit from his double strike at the Kassam Stadium.
"He's got good movement, good vision and he's a finisher as well," said Glenn after the game. "He showed his all-round game but it's early for him and it's Oxford in a pre-season friendly.
"More importantly, as a striker, he would have wanted to get off to a good start and he's done that. His potential is there for all to see. He has a lot to work with and that's the beauty off it.
"Both Helder Postiga and Bobby are young and who knows where they could go. They could both become top, top strikers. He's got a bit about him, nice touches, vision and I think he's a finisher.
"Sure, he's got to improve on certain things but it's important the fans have taken to the two young lads and they have to be patient with them. In time, I think they will do well for the club. We wanted options, certainly in the last third.
"That's where the cutting edge has to be. It's a long, hard season and you have to have that depth."
Glenn Hoddle says Bobby Zamora got the start that all strikers crave in his first game for Spurs against Oxford.
