James Tomkins feels the time he spent at the Olympics contributed to him losing his place in the West Ham side.
He made just a couple of appearances at the Olympics, and has since started just one game for the Hammers this season.
"It is always hard of course. I wanted to represent Great Britain and the manager gave me the chance," he said in the Daily Star.
"I went there expecting to play more than I did in the end. Obviously I wasted a lot of time and then Ginge (Collins) and Reidy played a lot together in pre-season.
"It was disappointing for me but I suppose that is what football is like."
