Leyton Orient boss Russell Slade admitted it was frustrating not to get a goal after his side were held to their second consecutive goalless draw.

The O's struggled to create chances as they were unable to break down Walsall at Brisbane Road in a dour contest. 

Slade said: "It is a little bit frustrating that we couldn't get a goal today but I'm very pleased obviously with the clean sheet.

"I felt we had a good pocket of play in the first half for 15 or 20 minutes and the same in the second half where we ought to have got a goal and on another day we would have done. 

"They got right behind the ball. They were organised and made life difficult to break down. They were tough opposition and they always are, but we worked their keeper a lot more than they did ours albeit we gifted them probably the best opportunity of the afternoon."

Orient have only won one of their first four League 1 games this season but Slade insisted that his side are improving and will continue to do so. 

The O's manager said: "As a group we're still a work in progress. I'm sure we'll improve and we are improving. There's no doubt about that, from the first game of the season to the matches away at Oldham and Bristol City and even again today. Defensively by and large we looked very sound."
