"He's the current North American Boxing Association heavyweight champion and he's ranked 14th with the WBA. It's very, very important for Joe to look good here. At the moment the heavyweight division is on fire and Joe needs to be hot in this performance to solidify his place as one of the elite heavyweights in the world today."
Parker, in his fifth week of training at his Las Vegas base during which he has racked up 67 rounds of sparring, saw several potential opponents come and go on the way to Winters' eventual confirmation.
"We all but had Robert Helenius signed," Barry confirmed. "We had offers to Gerald Washington, Christian Hammer, Johann Duhaupus, Erkan Teper, Mariusz Wach."
Parker is obviously eager to continue a comeback after the disappointment of 2018, during which he lost his WBO title to Anthony Joshua, and suffered a loss in his next fight to Dillian Whyte. The difficulties of his promoters - now Eddie Hearn's Matchroom – in finding suitable opponents were compounded last year when Parker was forced to withdraw from his fight against Dereck Chisora due to a spider bite.
"We were looking for that fight to really get us back in a good position and it didn't happen," Barry said.
"Joe focused on a lot of good strength work back in New Zealand in November and December. He's very strong and powerful at the moment and the camp is going well.
"I've been saying to him it doesn't really matter who we next fight – you have to look great. If we're going to put our hand up we have to show it out there."
