Errors from Dover Athletic goalkeeper Mitch Walker cost his side two goals in their defeat at home to Aldershot Town this afternoon.

Walker twice let the ball slip out of his grasp as the Whites lost 2-1 to fellow promotion chasers at Crabble.

Jim Kellerman and debutant Nicke Kabamba were on hand to punish the goalkeeper’s mistakes to give the visitors all three points.

Manny Parry cancelled out the Aldershot first goal within 60 seconds at the end of the first half but it was not enough to prevent the defeat.

A frantic couple of the minutes of the first half saw two goals and another ruled out for offside as the teams went in level at the break.

The winner was scored in the 66th minute by Kabamba and had chances to add their third late on as Dover surged forward looking for the equaliser.

The opening 30 minutes was very cagey with neither side able to take control of the game.

Dover had a good spell of chances 15 minutes before half-time but couldn’t find their way past the Aldershot goalkeeper.

Manny Parry headed Femi Ilesanmi's cross straight at Ward. Dover won the ball back almost immediately and Nortey's cross went right across the face of goal.

Ryan Bird had two good chances 10 minutes before half-time but couldn’t find the net. He controlled well in the area from Pinnock’s throw and had his shot blocked. Dover worked the ball over to the right and he couldn’t quite get his header on target.

Aldershot’s had a good chance of the half came in the 40th minute when Shamir Fenelon was through one-on-one with Mitch Walker. Bernard Mensah threaded through a lovely ball to find the Aldershot forward but he scuffed his shot well wide.

The visitors took the lead in the 45th minute when Mitch Walker spilt a dangerous free-kick into the box after Kane Richards gave away a needless foul. Walker appeared to have the ball safely in his hands but then dropped it to allow Jim Kellerman prodded home for the lead.

Dover hit back almost immediately when Manny Parry headed home a lovely cross from Pinnock on the right. Parry rose above his marker in the box to head into the corner.

Aldershot thought they were going to take a 2-1 advantage going into half-time when they had the ball in the back of the net. Walker didn’t deal with an Aldershot corner and the ball was bundled over the line before the referee blew up for a free-kick.

Giancarlo Gallifuoco forced an early save in the second half from the Aldershot goalkeeper when it looked like the ball was heading in. Dover won a corner through Kane Richards and Pinnock took the resulting set play, which Gallifuoco nearly headed home.

Dover were close to adding their second through striker Bird in the 62nd minute. Josh Passley played in a good ball to the forward who’s glancing header went just wide of the post.

Mitch Walker again failed to keep hold of a ball into the box to allow Aldershot to add their second. Bobby-Joe Taylor fired in a low cross and Walker palmed it into the path of Aldershot debutant Nicke Kabamba in the 66th minute.

Aldershot had chances to add their third late on in the game as Dover were chasing the game but looked assured as they held on to take all three points.
