Mick McCarthy went to watch ex-Cork City player Kieran Sadlier score for Doncaster on Saturday and strengthen his Irish ambitions.
Sadlier was named in the provisional squad for the double-header with Switzerland and Bulgaria but failed to make the final cut.
He was included on the basis of strong scouting reports so McCarthy decided to see the 25-year-old in the flesh on Saturday.
Sadlier did his case no harm by striking in a 2-0 win over his former club Peterborough.
"Terry Connor had heard good things about him from the Doncaster coaching staff and our scouts had seen him but I wanted to have a look at him with my own two eyes.
"I know all about the other options available to us so this trip to Doncaster made sense," said McCarthy.
"Kieran played well. He's been operating on the right side of late having started the season as a centre-forward and he took his goal well."
McCarthy's assistant Terry Connor will be on Troy Parrott watch this week, with the Dublin teen either involved in U-23 action against Blackburn tonight or in tomorrow's League Cup tie at Colchester.
Aaron Connolly is also on the radar after an impressive cameo for Brighton off the bench.
"Aaron was the one who really caught the eye with the 21s against Armenia," said McCarthy.
"He is getting game-time in the Premier League now with Brighton which will really benefit him and us and he was unlucky not to score at Newcastle.
"We are talking to Spurs and Terry will watch Troy this week."
The Irish boss has also welcomed Seán Maguire's goalscoring comeback at Preston after a freak eye injury halted his Irish ambitions.
Enda Stevens' suspension for the trip to Tbilisi next month has left McCarthy with a vacancy at left full-back. Matt Doherty and James McClean are the leading contenders to replace Stevens on a one-off basis. Doherty is back fit and involved at Wolves.
"The important thing right now for Matt and for us is that he is playing again," said the Irish boss.
However, Connor went to see Greg Cunningham line out for Blackburn at Reading over the weekend.
And McCarthy has also watched Ryan Manning adapt to his new role as left-back with QPR.
Ireland striker Callum Robinson believes any player who represents an international team at senior level should be tied to that country for the rest of his career, even if their first cap comes in a friendly match.
