They have however not really been that much of a sensation during Town's first four games of the season, in fact both have barely featured.
Is there something up? You could argue that it was only only Macedonia Shumi was playing for, and it was only Scotland he was playing against. But to put in a superb performance against, lets face it a national team which could soon overtake England in FIFA's world rankings is surely enough to merit a first team place!
So why isn't he playing regularly for Town? Jim and fans a like know he hasn't done anything out of the ordinary since his arrival and hasn't really showed he's Macedonia's answer to Steven Gerrard. He just looks an average Town player, another squad player.
This begs the question could it be down to management? Or even the coaching staff at Town?
Ipswich Town have seen a lot of youngsters with so much promise suddenly disappear from the first team all together in the past couple of years. Dean Bowditch and Billy Clarke are two, who are in the reserves and out on loan respectively.
Jim may need a shake up of his coaches to aid Town's once highly ranked youth system.
Shumi has seen him drop out of the starting eleven in recent times, and will find it difficult getting back in, especially with the recent arrival of Ivan Campo.
Meanwhile Garvan won a man of the match award for the Republic of Irelands U-21's, score two goals in the process.
Garvan recieved heaps of praise from the U-21 coach Don Givens.
"We know what Owen can do. Throughout the whole campaign he has probably been our best player. He is coming back from an illness and he hasn't played much for Ipswich this season.
"In Sofia [on Friday], he struggled with the pace of the game in the first half and improved in the second. Tonight he was wonderful from start to finish."
Yet again Garvan is another player who has not really featured much in the starting eleven in the early stages of the season.
Garvan has however been suffering from an illness, although he played a full 90 minutes for his national team a little over a week after being left out of the Ipswich sixteen altogether.
This would explain his absence from the Town line up.
Jim will now be hoping that the two players can continue their international form into their next Championship tie against Reading.
