Born in South Shields, Tyne and Wear, Crosby played his football for Aldershot, making 258 appearances between 1971 and 1980 and netting 21 goals. In an exchange deal involving Ian MacDonald he moved to York City and was a vital part of their 1984, record breaking, 4th division champions team. He also had loan spells at Wrexham and Cheltenham Town.
Coaching and management career
When Smith was sacked in 1991, Crosby took over as a caretaker manager until a replacement could be found. Sunderland struggled to find a new manager, and during this protracted period, Crosby took Sunderland to only the 4th FA Cup Final in their history. After sympathetic calls from fans, Crosby was formally offered the manager's post. Sunderland lost the final 2–0 to Liverpool. Despite reaching the Cup Final, Crosby failed to inspire Sunderland in the league, and he was sacked in February 1993 to be replaced by Terry Butcher.
In July 2004 Steve McClaren appointed Crosby as reserve team manager at Middlesbrough. When McClaren was appointed as England manager in the summer of 2006, new Middlesbrough manager Gareth Southgate appointed Crosby as assistant manager. He was released by Middlesbrough in June 2009, following their relegation to the Championship. In September 2009, Crosby took on a coaching role at Northampton Town. Following the sacking of Ian Sampson on 2 March 2011 he took on the temporary running of the club until a full-time replacement was found.
On 30 May 2011, it was announced Crosby would make a return to Oxford United in the role of Head of Youth Development.
Crosby was appointed chief scout at Birmingham City in July 2012 as part of Lee Clark's backroom staff. He briefly served as joint caretaker manager with Richard Beale after Clark was sacked in October 2014 – equalling the club's record league defeat by losing 8–0 to Bournemouth – and left the club following the appointment of new manager Gary Rowett.
