"It is some record and Paul got great accolades for that last year," said Parkinson ahead of the trip to Yeovil on Sunday. "He was top scorer in the FA Cup which is incredible.
"I said to the lads last year and prior to the Mansfield game, our club has got a great tradition in the FA Cup and we want to uphold that. Paul is building his reputation in the FA Cup and we are looking to add to both of those factors at the weekend."
Offering a wider evaluation of Mullin's time at The Racecourse Ground, Parkinson added: "Paul has been a great signing for the club. His goal return is outstanding. He has produced some magical moments along the way and there are plenty more stories to be written in his time at Wrexham."
