Montreal Impact midfielder Ballou Jean-Yves Tabla apologized for skipping training on Tuesday amid transfer links.
Sources on Monday said Tabla had told the Impact he wanted to leave after the MLS club rejected offers from Europe, and the 18-year-old did not show up to training the next day.
But on Wednesday, he said on Twitter that he was sorry for his action while acknowledging his "ambition" to go to a bigger club.
"Yes, I have ambition and I'd like to go to the top level in my career, but I'm aware that I have a deal with my current team that I must respect," he wrote in French.
"I never wanted to be a distraction, and every day I continue to want to help my team attain its objectives."
Chelsea has been linked to having interest in Tabla, but Montreal director Adam Braz said this week that the Impact had only rejected one offer from a second-division club in Europe.
