Sampdoria star Luis Muriel had told Chelsea and Napoli to forget about signing him in January.
The Colombian has impressed this season and is a wanted man ahead of next month's transfer window.
Chelsea and Napoli are both chasing the 25-year-old, but they have now been dealt a blow after he revealed he is staying at Sampdoria until at least the end of the season.
"In January I'll stay here, I won't move," Muriel told Il Secolo XIX.
"I've never felt as good as I do this season, I want to grow again and beat my record for goals in a season.
