It was the turn next of the other new arrival, Domoraud, to get in the action when, seizing on a flicked header from Matt Pattison, he strode through on the Woking left to test the Lewes keeper with a left-footed strike. On the quarter hour mark Danny Bunce tried an ambitious effort from 30 yards, the ball passing a foot or so over the bar. A minute later a good move involving Domoraud and Lambu ended in a scramble in the box. The ball reared up but wouldn't come down quickly enough to allow Gez Sole to get the ball on target.
