"We took a lot of positives from our game against Wales. We led 9-0 â00 Eoin O'Malley kicked three penalties for us â00 and did so well that the Welsh were only in our half for about a minute in the first half," he said.
"The second half just left us down. Being realistic, we have to work on those deficiencies that occurred in the second half and one of the problems may have been fitness.
"We have a lot of boys who are not playing regularly. Some of them are on the bench some weeks with their clubs. But we're hoping to develop our skills and those involved with the provincial academies will be involved in that process," McAleese explained.
It is important to note that before the Wales game, the U-19 squad had only had four weekend training sessions together and their clash with Italy next month is likely to be a better gauge of how their preparations are going for the World Championship.
McAleese and his management team have none of the players available to them from the Irish squad that finished fifth at last year's U-19 World Championship in Dubai.
The former Ulster mentor explained: "We are always going to be a year behind in that all the other countries can have players for a second year, but we cannot."
But he added that he will be able to "call upon players when they are finished with their respective schools cup competitions."
As a further part of their World Championship build-up, the U-19s will play Italy over the weekend of the Italy-Ireland Six Nations clash in Rome next month.
Looking ahead to the IRB tournament, McAleese feels that having the event on home soil "has its advantages and its disadvantages."
"Being at home will earn us greater support it also puts added pressure on the side to do well. We will assemble four or five days before the tournament and we'll give it our best shot."
