Ireland star Matt Doherty admits that coping with the lack of activity during the Covid-19 lockdown is a mental challenge as well as a physical one.
The Swords native should have had a busy spell to deal with, in line to play for Mick McCarthy's side in a hoped-for Euro 2020 playoff final against Northern Ireland or Bosnia on Tuesday and also Europa League action with his club.
But Doherty, like his Wolves team-mates, can only do solo training at home as all football activity is off.
"It's difficult as the type of thing we are doing now is even different from what we do in the off-season," Doherty said.
"In the off-season, you obviously have a return date and you are trying to keep your fitness up. Now, there is no real return date.
"I know they put one out provisionally, but I don't think anybody thinks that will be abided to.
"It's difficult. You have to have your own discipline in your mind to do it as there's nobody babysitting you.
"If you don't do it, that's on you. We have a GPS on, so they can track it. But it's not easy. It's more off your own back."
