Ole Gunnar Solskjaer has made his third Norwegian signing after Molde striker Jo Inge Berget completed his move to Cardiff for an undisclosed fee.
Solskjaer has already brought in midfielders Magnus Wolff Eikrem and Mats Moller Daehli from Heerenveen and Molde respectively.
Berget, who like Eikrem and Daehli shares an agent with Solskjaer, was out of contract with Molde in the summer and has signed a two-and-a-half year contract at Cardiff City Stadium.
Solskjaer said on Friday: "I'm delighted to welcome Jo to the club. He went through his medical last night and signed his contract this morning.
"He's a forward and a full Norwegian international and arrives on a very good deal for us. He knows the way I want to play, he's a secondary frontman and is a very strong and intelligent footballer. He'll do well for us."
The trio of Eikrem, Daehli and Berget may not be the big-name signings Cardiff fans would like to see, but Solskjaer has backed the trio to shine in English football.
"We are talking about three full internationals I have brought in for a very cheap price compared to what they give us," he said.
"They are long-term value for money.
"Of course they haven't played in the Premier League but they are all full internationals and I know them because I have had them before.
"I know their personalities."
Another man expected to complete a move to Cardiff is Manchester United winger Wilfried Zaha.
The 21-year-old has made just four appearances for the Red Devils this season, one of which came in the Community Shield win over Wigan.
A move to Cardiff would allow the England cap to gain regular first-team action, but Solskjaer insisted, contrary to reports, that the player has not had a medical.
''You have to ask Manchester United,'' said the Bluebirds boss. ''He is a Manchester United player. I cannot comment about players who are not Cardiff players. Nothing has been concluded.
"I can confirm he has not had a medical for Cardiff. I can say that. I don't know what he has done with other clubs but he has not had a medical with Cardiff."
Cardiff are also close to completing a deal for Wigan defender Ivan Ramis after having a bid accepted by the Sky Bet Championship club.
Cardiff are currently bottom of the Premier League and, with survival the priority, Saturday's trip to Bolton in the FA Cup may be a fixture Cardiff could do without.
But Solskjaer wants his side to use the fourth-round tie as a means of generating momentum.
He said: "Tomorrow is going to be an important game for the club.
"It is vital to build momentum and confidence. I hear many people say it is a distraction but for me it is another chance to get to know the lads and for them to implement what we are trying to do.
"The FA Cup was the biggest one-game occasion in football. I watched probably all of them. This is one final we really want to get to and this game is massive for us.
"But we need fresh legs and energy, especially mental energy, we need to rotate as we have another game on Tuesday and then Saturday."
And the Norwegian has urged his players to believe they belong at the elite level.
"Sometimes they need to get told they are better players than they think they are," he said.
"You cannot outperform your ego. So, they have got to start believing that they belong in the Premier League and that they should be playing against the Manchester Citys and the Manchester Uniteds."
