Wellington wrapped up their season with a 4-1 loss to the Melbourne Victory in Wellington on Saturday night, conceding a league-worst 51 goals this summer.
"Every season's emotional. I've got to try and lead the team and find ways to try and help motivate and get the team firing," Durante said.
"So I take a lot of that on my shoulders and I go home and think about it quite a lot, so it's been difficult. We've conceded a lot of goals and I'm at the back and I take that pretty hard, so it's draining in that sense."
Wellington's season can be split into three clear parts as they failed to win a game in their first 10 contests, then enjoyed a strong run of form, but flopped in the final third.
Merrick will now make some quick calls regarding off-contract players and he got the ball rolling yesterday with confirmation that striker Stein Huysegems and veteran utility Leo Bertos won't be back next season.
"I know Stein will be a very competitive player wherever he ends up and if we have to face him I expect him to give us a tough time," Merrick said.
Finding quality midfielders and another striker are top priorities for Merrick, who will now look to the free-agent market.
