The talented centre back battled with hamstring issues during his brief time at the club and has now returned home to his family.

Out of the seven Visa players United has had, only captain Ashley Dunn and coach James Coutts, who is now an Australian resident, have stood the test of time.

Dunn said it was unfortunate the club didn’t get to see the best of Posada, who never really got settled.

“He got injured, didn’t have a job and was missing his family, so it was quite difficult, but I’m sure he’ll do alright in the future,” Dunn said.

“You want to try get into a bit of a routine, if you’re just training and not doing anything during the day, you’d probably get a bit bored.

“The main reason was him being injured, if he was playing each week and he was fit, 100 per cent he would have stayed.”

Fortunately, United won’t have to wait long find a replacement, with the transfer window opening in May.

“We’d be looking for the best (we could get), ideally another defender or a forward/striker that could help Archie (Thompson) and the boys up front,” Dunn said.

“It's really whatever becomes available, it’s halfway through the season and it’s a big commitment because the season only goes until September.”

While he admitted it can be tough to maintain a Visa player, Dunn believes the recent success of the club will attract more prospects.

“I think you can see the silver lining and it feels like we’ve finally got a good squad together after the first three years and the results are showing that,” he said.

“There’s obviously still a long way to go, but I think we’re over the hill with the really hard years and now its just about building what we’ve got.

“It’s really important that everyone keeps investing in the senior squad because there’s no point doing well this year and players go and we’re back to square one.

“We don’t want to be fighting relegation, we want to be pushing for promotion.”

United will look to extend its unbeaten run to six matches when it faces Bendigo City away on Saturday.

“I still think we’ll be the underdogs, but I think it’s the most important game of our season,” Dunn said.

“We need a good result and we’ll keep taking it week by week and hopefully keep pulling away.

“We’ve drawn against the top teams in the league (Dandeong City and Dandenong Thunder), so there’s nothing to fear, as long as we work hard we always fancy ourselves.”
