Daehli, a January signing from Molde, was a constant threat in Saturday's 1-1 draw with Stoke, which edged Cardiff closer to their relegation rivals.
Solskjaer is delighted with Daehli's recent form and believes his fellow Norwegian has been a driving force in Cardiff's midfield.
"He is proving time and time again that he is worth a place in the team," said Solskjaer .
"He gets you on the edge of your seat, he does things, the difficult things at times, and he is fantastic at just playing simple when that is required.
"He's a good footballer, and I think he has done fantastic since he has come here."
The Welsh side have picked up five points in their last four games and Solskjaer also singled out the contribution of goalkeeper David Marshall.
Scotland international Marshall has received praise for his performances throughout the season and earned more plaudits for a late point-blank save to deny Stoke's Oussama Assaidi.
"The first 75-80 minutes I thought we deserved more than a draw," Solskjaer added.
"Towards the end, though, you might say we didn't deserve anything. We have a top, top goalkeeper and he saved a point for us. We thank him again.
"He has just signed a (new) contract, and we are going to make sure he doesn't have the option of going down. We have three games to rescue the season."
Cardiff have just three games left as they attempt to haul themselves to safety - away to Sunderland and Newcastle, then at home against Chelsea.
Solskjaer believes his side might need just six points to secure their Premier League status.
"Two wins would be enough, but you never know in this league," he said. "You never know what the outcome is going to be in any of the games.
"It is not a miracle needed, but it is two very good performances needed in the next two games to give us a chance in the last game against Chelsea."
