Leyton Orient boss Russell Slade admits his side will need to improve if they are to win the League 1 play-offs after the O's lost 2-1 at Crawley Town.

Orient's defeat this afternoon helped Brentford clinch automatic promotion and the O's must now focus on finding top form heading into the play-offs. 

Slade said: "We just have to keep plugging away. It is what it is now, I think that's what you've got to say. It's the play-offs and we have to embrace that now and be positive. 

"We have to improve. I asked for improvement before the game and that's why because we need to be better if we're going to go up via the play-offs. We need to make sure we're performing at a very, very high standard."

The O's fell behind against the run of play through Gwion Edwards and although Chris Dagnall equaliser, Andy Drury headed the second-half winner. Both Crawley goals were sloppy and the manager admits they made life difficult for themselves. 

Slade said: "I am disappointed in the goals conceded. I haven't seen them because we haven't been able to take the footage and it's always nice to have a look at them. But they didn't look good goals I have to say.

"If you concede goals like that then it's always going to be a worry and a bit of a fight to try and get back into it. 

"I thought we created a few chances in the first period and had a good foothold in the game when they actually scored. But obviously we've not picked up runners and not seen the danger quick enough. On the second one it looks like we haven't marked at all."
