O’s defender Callum Kennedy cut a frustrated figure on Saturday as another goal from a set piece proved decisive in the 1-0 defeat to Portsmouth.
Christian Burgess’ header separated the sides at the Matchroom Stadium, and the 24-year-old was disappointed with the manner in which the O’s conceded.
“Performance wise we have worked our socks off and put everything into the game but it is very disappointing that another set piece has lost us the game,” he told leytonorient.com.
“It is disappointing, especially working as hard as we did and aside from the set piece we didn’t really feel threatened.
“I thought we started the game well and in the first five minutes we created a couple of chances and I thought we could have nicked a goal, but I didn’t really feel like we were under the cosh. It is just extremely frustrating when you concede from a set piece which in my eyes is a sloppy goal to concede.”
Chances to get back in the game were few and far between after Pompey took the lead, and Kennedy added: “After they scored the dynamics of the game changed as we wanted to get back in the game but we couldn’t really string passes together and it was a bit bity.
“They were good at breaking it up and slowing the game down when they needed to. It’s just one of those afternoons where everyone goes home frustrated.”
After a congested first week for Orient boss Cavasin with both Tuesday’s Checkatrade Trophy tie and then Saturday’s game, Kennedy is looking forward to a solid week on the training pitch ahead of this weekend’s home encounter with Luton Town.
“It’s been good, but hard because we have had two games and only really had one training session with Thursday acting as a recovery for those who played on Tuesday at Southend,” he added.
“We did bits and bobs on tactics but it is not as intense as he and we would have liked it so we haven’t had bundles of time together yet. He likes to get the ball down and play, which we tried to incorporate today.
“It is definitely something we will be working on and so far the manager has been very positive. He has got a good manner about him and it is just one of things that we will work on.
“We need to get our heads down and I am firm believer you get out what you put in and the only way we can get out of that is if we work hard.
“The more time we get on the training pitch the better, especially if he wants to change certain aspects of how we want to play. It takes a little bit of time.
“It is one of those things where you need hours on the training pitch to get used to it all, but I think we are more than capable if anything is to come up during a game and we should be able to adapt and overcome it.”
