Thame had Nik Rhodes to thank after his double sealed victory at Kidlington 2-0 and maintained their six game unbeaten streak in the league.
Assistant manager Steve Meredith said: “We have stretched our squad quite considerably and the lads have done really well.
“We are defending as a team a bit better now. That’s not just the back door being bolted that’s as a team.”
Thame’s first goal came after 11 minutes when Rhodes got the final touch on a free-kick, deflecting it beyond the keeper’s reach.
United withheld some decent pressure from Kidlington before Rhodes finally made the points safe with a well placed drive.
It was Rhodes’ third goal in two games after he scored a superb diving header in the 2-1 win at Holyport last Saturday.
Despite their fine form Meredith warned against rising expectations.
“We have to be realistic as a club. Other clubs are stronger financially. Last season we punched above our weight and we are again this season.”
United host Newbury Town in the Bluefin Challenge Cup second round on Saturday (kick-off 3pm).
