Input: Question: When was construction completed on the stadium where Wilkins remained until July 1982? Passage:Able to play on either flank as a full back, Wilkins began his career at Chelsea at the age of 10 and signed his first professional contract in 1972. He remained a bit-part player until the 1976–77 season, when he made 29 appearances to help the Blues to promotion back to the First Division. Wilkins remained at Stamford Bridge until July 1982, by which time he had made 151 appearances and scored one goal. He dropped down to the Third Division to join West London neighbours Brentford on a free transfer, but with the Bees he experienced "the worst two years of my life. I dislocated my shoulder, had seven teeth kicked out, ruptured my cruciate ligaments and that was it". Wilkins' final appearances as a professional came late in the 1983–84 season, on loan at Third Division club Southend United.
