Republic of Ireland striker Shane Long has vowed to learn lessons from his side's defeat against Poland in last night's friendly.

Long, who scored the opening goal in the 2-1 home loss, failed to convert a couple of chances after being played in by Wes Hoolahan to seal the victory.

"Nine out of 10 times in training you'd take [those chances] and sadly they didn't go in for me today," the 27-year-old is quoted as saying by the Irish Times. "It's nice to get a goal, nice to play up front with Wes as well, I think he enjoyed setting me up and it's a striker's dream when you have someone like Wes behind you.

"I think the second chance I had the keeper gambled you know and read me like a book, and the third I just kind of dragged it a little bit but I'll learn from it and luckily it wasn't in a qualifying game.

"I should have finished them, there's no denying that. It's frustrating but I can take a lot of positives from it. It's a friendly tonight and the gaffer tried out a few things and hopefully I gave him a few things to think about."

A James McCarthy own goal and a close-range strike from Filip Djordjevic ensured that Serbia left the Aviva Stadium victorious.
