The Norwegian midfielder has joined the Bluebirds for an undisclosed fee from Eredivisie outfit Heerenveen and will add some much-needed creativity.
Eikrem was spotted in the crowd at St James' Park on Saturday, watching his new employers' 2-1 win over Newcastle United, and Solskjaer is now able to link up with the former Manchester United youngster once again.
On Eikrem, the 40-year-old manager told the club website: “He’s a play-maker, a quarterback if you will, someone who likes to get on the ball and can see a pass. He’s technically very good, including set pieces and has great vision."
Here are five facts about the Bluebirds' latest acquisition...
1) Eikrem started out at local club Molde FK at the age of 12, after starring at one of Solskjaer's soccer schools, despite the schools being designed for 14-16-year-olds.
2) Manchester United snapped him up at the age of 16 after he impressed coaches with his rapid progression. Eikrem left the club in 2011 having made no competitive first-team appearances for United before moving to Molde, who Solskjaer would later go on to manage.
3) The 23-year-old was one of two players to miss in a penalty shootout for Manchester United's under-18 side in the final of the FA Youth Cup, which United lost 4-3 to Liverpool.
4) Eikrem is the son of former Molde player Knut Hallvard Eikrem, who made over 220 appearances for the Tippeligaen outfit.
5) At the age of 17, Eikrem was diagnosed with diabetes. The illness prevented him from playing football for around six months, during which time it is rumoured both Sir Alex Ferguson and Cristiano Ronaldo personally visited him.
