Young midfielder Adam McDonnell made his Republic of Ireland U18s debut but his side lost the first of two friendlies in Portugal 2-0 earlier this afternoon.
McDonnell started the game, which was played in Abrantes, and played the first 58 minutes before being replaced. The Irish youngsters take on the Portuguese in the second friendly of their trip in Bonitos on Thursday.
After the game the 17-year-old tweeted: "Some game against Portugal, bad result lost 2-0 but they were sick! Good experience."
Midfielder McDonnell joined the Blues on a two-year deal from Shelbourne close to the end of the transfer window following a trial in the summer.
The Dubliner recently made his first two appearances for the Irish U19s, adding to caps at U16, U17 and Emerging Talent levels.
Town are still waiting to receive McDonnell’s international clearance from FIFA and he is yet to appear in a competitive game for the Blues' U18s or U21s.
However, he has played in friendlies and has already trained with the first team, impressing manager Mick McCarthy, and once available is likely to come into consideration for the Blues boss’s senior squad.
