Lions boss frustrated that his team's second-half display isn't rewarded
Despite turning in a slightly below-par showing in the opening 45 minutes, Chopper's charges really gave the visitors some uncomfortable moments after the break, dominating a second-half in which they twice had penalty appeals turned down and also hit the woodwork through sub Alfie Pavey.
Lalkovic's winner on 29 minutes came following a defensive slip by youngster Sid Nelson, with the Saddlers midfielder calmly slotting the ball past keeper David Forde.
"It was another poor goal to give away again," rued Chopper. "I seem to say this every time we speak, but before that they had had a lot of possession between the two boxes but never penetrated our defence or had a shot on target.
"We were frustrated to be a goal behind and then you are chasing the game. Before their goal Steve Morison put the ball the wrong side of the post and their keeper makes a good save from Aiden (O'Brien) so they might have had the possession, but we should have been in front.
"At half-time I said to the boys to be a bit more aggressive in getting the ball and pressing higher up the pitch and in the second-half it was all us. We hit the bar, we had numerous scrambles in the six-yard box and the keeper made a great save right at the end but we just couldn't get a goal.
"I'm disappointed for the players today, and the fans as I felt we deserved something from the game. Walsall showed their quality at times, but we should have been coming off talking about getting a draw at least and how we dominated in the second-half. We should have won the game but are standing here with nothing."
