 On 10 May 2011 McGleish was released by Leyton Orient after his fourth stint with the club, despite being the club's top scorer of the 2010–11 season with 17 league goals.He had performed well as mentioned above, making his presence felt all over the pitch without fouling, and poaching goals by quickly taking advantage of space and opportunities.It was felt by fans that he had matured with age and news of his swift departure at the end of the season was met with surprise; not least as the club stated that it was looking to increase front line options.
