Crewe Alexandra's Adam Dugdale says he is relaxed about the prospect of a new central defender joining the club.
Four trialists have been and gone this summer as Crewe look to improve one of the worst defensive records in the lower divisions.
Dugdale told BBC Radio Stoke: "I know Dario wants to add a defender. He's said that all along. But as long as I perform that's all that matters to me."
The 23-year-old made 21 appearances for Crewe last season.
Dugdale joined Crewe Alexandra for the second time in July 2010 after a successful trial period, having left the club in 2007 without a first-team appearance to his name. During a three-year spell in non-league football, he played at Barrow, Southport, Droylsden and AFC Telford.
"I am feeling a lot fitter having done another full pre-season, and my aim now is to cement a regular place in the team.
"We all know we need a couple of new signings to boost the squad, but if a defender comes in then so be it - I thrive on a challenge," added Dugdale.
Crewe conceded 65 league goals last season, and the 47 they conceded away from home was the highest in League Two.
