Dimech's second season with Mansfield Town was quite indifferent in the early part of the season; Keith Curle was sacked and replaced by Carlton Palmer. Dimech carried the good form he enjoyed the following season and cemented a place in the heart of the defence, Dimech did not enjoy the best of second halves of the season and after falling out of favour with Carlton Palmer, Dimech was released at the end of the 2004–05 season. In two seasons with Mansfield Town, Dimech made 45 appearances and scored one goal.
