Dunne is hoping to establish himself at the New Den next season

The 22-year-old told the Lions' website: "I've been offered a new contract, and I want to stay and help Millwall push for promotion.

"It was a frustrating end to last season after getting a six-match suspension and then an injury. Before that, things were going well.

"Now I'm looking forward to coming back after a bit of a rest, and I'm hoping to establish myself as a regular."
