Cardiff City have made the right decision to sell Mats Moller Daehli to Freiburg, according to former player Jason Perry.
The 19-year-old Norway midfielder will join the German Bundesliga club on 3 January for an undisclosed fee.
Ex-manager Ole Gunner Solskjaer signed Daehli but he has had a limited role under new boss Russell Slade.
"He doesn't fit in with Slade's way of playing, which a number of players don't in that squad," Perry said.
"It lacks balance, it's been brought together without any thought about systems."
Daehli joined Cardiff in January 2014 and made 16 appearances last season, scoring one goal, and was a regular at the start of this season under fellow Norwegian Solskjaer.
But the youngster, who has won 11 caps, has made only two substitute appearances in the Championship since Slade's appointment as manager.
"What you have with Daehli is a lot of people enjoy watching him; he's good in tight positions, he keeps the ball, he's brave, gets on the ball but there's no end product," Perry said.
"He doesn't put any telling crosses in, he doesn't see the pass like Aaron Ramsey used to at a young age and split defences.
"So he doesn't effect the game enough to give him that free role, you've got to be a good player just to play behind the front man or to dictate the whole game and he's not there yet.
"He may be in years to come but he's not there yet and Cardiff need players to come into that squad that can help them now, they can't wait.
"So as long as they've sold him for a profit, as long as that money is reinvested into the side then I think it's a good decision."
The Bluebirds are next in action when they travel to Charlton on Boxing Day and then play Watford at home on Sunday, 28 December.
