Leyton Orient manager Justin Edinburgh said his side were “totally the opposite” to their previous week's defeat at home to Salford City after beating Wrexham on Saturday,

The O’s defeated their fellow promotion Wrexham 1-0 at the Racecourse Ground in the second round of the FA Trophy thanks to Matt Harrold’s second-half penalty.

Speaking to the club’s website, Edinburgh said: “We spoke about that [bouncing back] before the game. We were disappointed in the scoreline last week and from the outside looking in, people were probably thinking that we made a lot of changes and perhaps we were coming here with a weakened squad and we were totally the opposite to that.

“We came here with a real belief and a real good away performance and it was an excellent victory.”

Harrold started up front with James Alabi in place of usual strike force Josh Koroma and Macaulay Bonne and stepped up to score the winning goal just after the hour mark when Wrexham captain Mark Carrington brought down James Brophy in the box.

Edinburgh said: “We’re so used to Macaulay (Bonne) stepping up and dispatching them but Matt, I had every confidence in him, he was assured and dispatched it excellently.”

Orient were made to work hard in the final 12 minutes after Myles Judd was dismissed for a second bookable offence, leaving Edinburgh disappointed in his player.

He said: “Since I’ve been in charge, I’d expect those performances from last year. It was a bit reckless, a bit gung-ho. He’s improved a hell of a lot but today was a performance where he played for himself and that disappointed me. Unfortunately we’ve lost him for a game and he may have cost his team but they held on for him.”

The line-up also saw 33-year-old Dean Brill continue to start in goal ahead of youngster Sam Sargeant.

Speaking about the decision, Edinburgh said: “I just feel Dean needs to play. I think Dean, as a goalkeeper, doesn’t want to miss games, he’s been restricted with his training of late and we need to keep playing him.

“When you make so many changes, I think it would be a little more difficult for Sam as well to come into a team where it’s near enough a new back four and I think with Dean’s experience and presence it gives that assurance to the back line.”

Orient’s next game sees them return to league action with a trip to Ebbsfleet United on Saturday at 3pm.
