Wolleaston is looking to establish himself at Cambridge

The 26-year-old has agreed non-contract terms at the Abbey Stadium following his departure from Oxford in October.

Wolleaston, who started his career at Chelsea, signed in time to make his debut in Cambridge's defeat at Altrincham on Saturday.

Meanwhile, U's boss Rob Newman has released defender David Chick, 25, following six Conference appearances earlier this season.
