Dover manager Martin Hayes has signed former Billericay central defender Bobby Aisen.

Hayes (pictured) was on the lookout for more defensive cover and has opted for Aisen, who was highly recommended by Rushden boss Justin Edinburgh.

"We needed some cover at centre-half, as we only really have Dean Hill as back-up in that position.

"Bobby was at Wingate and Finchley when I was there very briefly. I didn't really know him that well as I was there for a short time and he was a very young player.

"But since then he has played in the Conference and is a strong lad. I am happy to take him on board to battle it out with the other lads for a starting spot."

Having started his career with Peterborough, he joined Wingate & Finchley in 2007. Aisen signed for Rushden last summer but within a month he joined Kings Lynn on loan before completing a permanent move in October 2009. He also featured for Billericay at the end of last season.

Aisen played for Whites in pre-season against Carshalton.
