With fewer local fighters coming to his gym, Dann began looking abroad for talent.
It led to him finding the 6ft 3in (1.9m) southpaw from a country sandwiched between Romania and Ukraine in eastern Europe.
“I have one friend here, he’s been here for 10 years now, and he met Marlee,” explains Ursu.
“They had a chat and said ‘we have someone in Moldova’.
“At the time I didn’t want to move. I was comfortable in my country and staying home. I have a good family, good friends.
“Then Marlee messaged me and said ‘come for a month’, after this month it’s been seven years now.”
He added: “Plymouth is very safe city. It’s quiet, it’s peaceful, there’s good people around, everyone wants me to do very good in life and everyone tries to help me.
“It’s very easy in life when you have good people around and they want only good for you, it’s very easy to achieve something.”
For Dann, who has seen Ursu sparring at close quarters for the past seven years, that ‘something’ could be huge.
“I’ve seen Constantin in the ring with world champions, I’ve seen Constantin in the with European champions, British champions. I’ve never seen anyone get the better of Constantin,” he says of his fighter who won a silver medal at the 2015 European Junior Boxing Championships before winning a bronze three years later.
“It’s kind of one of those situations where you’ve seen it, and if you see it, you believe it.
“For me it’s one of those things where I just think Constantin’s going to do it.”
