Leyton Orient boss Ian Hendon has threatened to make changes and has forced his players to come in for extra training tomorrow after their defeat to Accrington Stanley which he described as "not acceptable".

The O's were booed off the pitch after a dismal performance and the head coach made his feelings abundantly clear following the match.

Hendon said: "Disappointment is the biggest understatement. That's just not acceptable. 

"We've just looked in there and we've had a discussion if you want to call it that. I've just looked through some of the clips of the game. If you don't take your chances you don't win games. We had some good chances in that game. 

"I'm not saying we played well because we didn't. I'm not going to disguise that fact but we had some very good opportunities to score and we didn't take them."

Hendon continued: "We've had six or seven good chances and they've probably had two. They had a few from distance but I'm not papering over any cracks here. That was not good enough by any stretch of the imagination and I will be dealing with that.

"I've just spoken to them and we shall be here training tomorrow and we will get it right."

Orient are seventh in League Two but have only taken 11 points from as many league matches after winning their first five games. 

Hendon is prepared to make changes and would consider bringing new players in despite previously insisting he was happy with his squad.

The head coach said: "We do work on the training ground and we've done a lot of homework on them. That is exactly what we've shown them on the video for two days now how they play, what their strengths are. Josh Windass breaking from midfield and Billy Kee getting hold of the ball which he is very good at. 

"That is where the goal came from and you can only put that down, tell them what they do, show them what they do on the training pitch and if they don't take it on board and make mistakes like they did today then we're going to have to make some changes."
