McCarthy was at the Keepmoat Stadium on Saturday as former Cork City and Sligo Rovers striker Sadlier scored in Doncaster’s 2-0 League One win over Peterborough while Preston’s Maguire was watched as he netted in a 1-0 win at Birmingham.
Neither player featured in the recent games against Switzerland and Bulgaria. Sadlier was named in the provisional squad while Maguire was forced out of the final squad with a freak eye injury picked up in training.
“I’ll name the squad for Georgia and Switzerland on Tuesday week and I wanted to have a look at Kieran for myself,” McCarthy told FAI.ie.
“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.
"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.
“Sean scored again as well which is great news. He was very unlucky with the injury that kept him out of the Swiss and Bulgaria games so it’s good to see him back and in the goals again while Callum Robinson is also fit and back in the Sheffield United team.”
McCarthy and his staff are keeping on eye on emerging talent as well with the manager up to date with Aaron Connolly’s progress at Brighton while Troy Parrott will be watched by assistant Terry Connor this week.
“Aaron was the one who really caught the eye with the 21s against Armenia. 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,” added McCarthy.
“We are talking to Spurs and Terry will watch Troy this week in the Under 23 game at Blackburn on Monday or the Football League Cup match against Colchester on Tuesday night if he is involved in that one.”
Assistant manager Connor was at Reading on Saturday as Greg Cunningham, Darragh Lenihan and Derrick Williams helped Blackburn Rovers to a 2-1 away win while James McClean was watched in Stoke’s scoreless draw at Brentford.
“With Enda Stevens suspended for the Georgia game, we are looking at left-back options,” added McCarthy.
“Terry saw Greg play there for Blackburn, we had James watched for Stoke and I saw Ryan Manning play for QPR against Luton last week.”
Pleased to see Jeff Hendrick and Callum O’Dowda start for Burnley and Bristol City respectively on Saturday, McCarthy has kept in touch with Matt Doherty after his return to first team action with Wolves following a knee problem.
“The important thing right now for Matt and for us is that he is playing again,” concluded the Ireland boss as Wolves went to Crystal Palace on Sunday and Doherty played for almost an hour of the 1-1 draw.
