Wilfried Zaha has joined Cardiff on loan from Manchester United until the end of the season.
Ole Gunnar Solskjaer had already boosted his squad with the additions of Fabio, Kenwyne Jones, Magnus Wolff Eikrem, Mats Moller Daehli and Jo Inge Berget since succeeding Malky Mackay as Bluebirds boss.
Zaha, 21, is the most high profile of his acquisitions, although it has taken longer to conclude the deal than had been expected.
The England U21 has found first-team chances difficult to come by since David Moyes's arrival and Solskjaer said: "That signing should be done by now. His name is on the paperwork. He is a Cardiff player.
"He has pace, power, technical ability and goes past people. He will give us that extra change of tempo in the final third, where we really need it.
"He will bring that little final bit to find pockets of space and produce a bit of magic."
But the Norwegian does not believe Zaha has anything to prove, despite his limited opportunities since moving to Old Trafford from Crystal Palace.
He has made just four goalless appearances for United this season but former Red Devils striker Solskjaer said: "I don't think he has something to prove, he wants to play. He played a few games at United, but maybe not what he hoped for when he went there.
"He wants to play, to play with confidence and keep Cardiff in the Premier League."
Solskjaer also confirmed striker Andreas Cornelius, signed for £8million by Mackay last summer, is in talks over a return to FC Copenhagen.
He said: "Andreas is speaking to Copenhagen, it is not 100 per cent done yet. We will confirm when it happens.
"He has had a hard time, he came here with big potential, he is a young kid and young kids are not the ones you expect to carry a team. He is a young man who will play a lot of good football in his career."
