Born in Molde, Eikrem began his football career as a 12-year-old with his local club, Molde FK. He was picked up after he attended one of Ole Gunnar Solskjær's soccer schools in Norway, despite the schools being for youngsters aged 14–16. Nevertheless, he impressed the coaches so much that they allowed him to attend, and he was signed by Manchester United on his 16th birthday.
Manchester United
Eikrem was a regular starter for the United under-18 side in the 2006–07 season, and helped the team to the final of the FA Youth Cup, where they lost to Liverpool 4–3 on penalties after the two-legged match finished 2–2 on aggregate. Eikrem was one of two United players to miss a penalty in the shoot-out, the other being captain Sam Hewson. Eikrem also captained the Manchester United youth team to the final of the 2007 Milk Cup but United lost in stoppage time to Brazilian side Fluminense. A few days later, he played in his first game for the Manchester United first team, coming on as a substitute for Ryan Giggs in a 4–0 pre-season friendly win away to Dunfermline Athletic. Eikrem continued as a regular member of the under-18 side throughout the 2007–08 season, making the odd appearance on the reserve team bench, before becoming a full member of the reserve side in 2008–09. During the season, he helped United to second place in the 2008–09 Premier Reserve League, as well as a cup double over Bolton Wanderers in the Manchester and Lancashire Senior Cups. After playing in the reserve team's first four games of the 2009–10 season and scoring in a 2–1 league win over Wigan Athletic, Eikrem was rewarded by being given the number 42 shirt for the first team's League Cup third round match against Wolverhampton Wanderers. For the 2010–11 football season, Eikrem was named as a member of United's Champions League squad. He was named as a member of a "B-squad" alongside several other younger players such as Will Keane, Joe Dudgeon, Oliver Gill, Ben Amos and Corry Evans.
Molde
In January 2011, Eikrem transferred back to Norwegian team Molde, who were managed by former Manchester United reserve team manager Ole Gunnar Solskjær. In his first season, Eikrem was involved in the Molde squad that won Tippeligaenfor the first time. He helped successfully defend the title in the 2012 Tippeligaen season.
On 24 June 2013, Eikrem signed a four-year contract for Heerenveen. He made his debut in the Eredivisie in a 4–2 home win against AZ. He scored his first goal for Heerenveen on 23 August 2013, against defending champions Ajax.
On 8 January 2014, Welsh side Cardiff City announced that Eikrem had signed a contract with the club, for an undisclosed fee and duration. He made his debut three days later, coming on as a 66th-minute substitute for Gary Medel in a 2–0 home defeat against West Ham United. He went on to make six top-flight appearances as Cardiff were relegated back to the second tier. After a poor start to the 2014–15 season, Solskjaer was sacked and his replacement, Russell Slade, placed Eikrem on the transfer list. On 19 December 2014, Eikrem had his contract terminated by mutual consent after not playing under Slade.
On 26 January 2015, Eikrem signed a three-year contract with Swedish champions Malmö FF. On 22 February 2015, Eikrem scored one goal and made two assists in his first competitive match for the club, a cup fixture against Assyriska FF that Malmö won 3–0.
Eikrem joined Seattle Sounders FC on 30 January 2018. He was waived on 20 July 2018.
Molde return
On 25 July 2018, Eikrem returned to Molde after five years away, signing a four-and-a-half-year contract. The day after, on 26 July, he made his first appearance since returning to the club as a 65th minute substitute in a 3–0 home victory over Laçi in the Europa League. He played an important role in Molde's title-winning season in 2019, and was nominated to the Eliteserien Player of the Year award. Eikrem finished the 2019 season with 13 goals in 33 appearances in all competitions. Ahead of the 2020 season, on 17 January, Eikrem was announced as Molde's new captain.
