Oxford have signed Northampton captain Chris Willmott on a Bosman-style free transfer, and he has agreed a two-year deal at the Kassam Stadium. The 27-year-old defender told Oxford's website: "I was told that Oxford were interested and came down for a meeting with (manager) Brian Talbot.
"This is a new challenge for me, which I am looking forward to."
Wilmott made 82 league appearances in two seasons at Sixfields, following spells with Luton and Wimbledon.
