Real Madrid's James Rodriguez says he is considering his future and may depart during the January transfer window.
The Colombia international says he is happy in Spain but wants more playing time, having been in and out of the line-up since Zinedine Zidane took charge.
And the 25-year-old was an unused substitute on Sunday when Real defeated Kashima Antlers 4-2 in the Club World Cup final in Yokohama.
After the game, James said: "I can't assure I will stay at Real Madrid.
"I have offers and seven days left to think about my future.
"I am happy in Madrid, but I want to play more. I have a bitter feeling as I wanted to play the final, but I am happy for the title. It's the 15th title in my career."
English national newspapers have reported that Premier League-leaders Chelsea are interested in James, who is reportedly seen as a possible replacement for Oscar if the Brazilian goes to China, and claim he could cost £75m.
James was one of the stars of the tournament at the 2014 World Cup, scoring six goals in five games to land the Golden Boot award, as Colombia reached the quarter-finals.
Having previously moved to Monaco from Porto for £38.5million in 2013, he was transferred to Real after the World Cup for £71m.
He has scored 21 times for Real since the move but has only found the net twice for the Champions League holders this season.
