Daehli, who came through the Manchester United academy, featured 13 times for Cardiff since arriving from Norwegian club Molde FK in January 2014. The 19-year-old midfielder scored one goal as the Bluebirds failed to remain in the Premier League, although the Norwegian international drew plaudits for his work rate and passing ability, WhoScored record a 89.3% pass success rate for the youngster.
These talents did not go unnoticed in the Premier League, with The Independent suggesting that Jose Mourinho was scouting the player as he looks to rebuild his young, hard-working Chelsea side with cheap, home-grown players - which Daehli, due to his spell with United, would count as.
The transfer certainly makes much sense from a Chelsea perspective, although the player's career could potentially suffer if he leaves the club he joined only a few months ago.
Cardiff manager Ole Gunnar Solskjaer, who signed Daehli for Molde, as well as Cardiff, has already expressed his intention to return to the Premier League at the first attempt, and the Old Trafford legend has started at this early date.
Austrian midfielder Guido Burgstaller and Spanish striker Javi Guerra have already been signed from Rapid Vienna and Real Valladolid respectively, and Solskjaer can be delighted that Daehli has now revealed he intends to see out his contract with the Welsh club.
Speaking to Norwegian media outlet VGSporten, the 19-year old laid out his future plans, plans which do not involve a move away from Cardiff.
When asked whether he hopes a Premier League buys him, Daehli responded: "No, there is no point in dealing with it. Just focus on what comes now."
"First is the main squad. I'll take a little vacation, and then it's back to training, and to continue to develop myself."
"There is certainly a lot to think about concerning me and my future. But to play every week with a manager who believes in you, and that I have developed under, is good for me."
Cardiff fans will be delighted to know that their starlet is set on his future with the club, as the Bluebirds look for another successful season in the Championship.
