After a week of rumours, it was official on 10 September 2009 that Arvesen would be joining from the 2010-season, along with fellow Norwegians Edvald Boasson Hagen and Lars Petter Nordhaug. The start of the 2010 season with Team Sky was marred by injury for Arvesen. After winning the 1st stage of Tour of Qatar (TTT), Arvesen crashed on the following stage, breaking his collarbone. He returned to the bike in time to participate in Tirreno–Adriatico.
