Alexandre Pato's agent has confirmed that Chelsea have made a bid for the Brazilian starlet, but Real Madrid, Milan and Internazionale are also in the reckoning.
The English giants have emerged as favourites to land the 17-year-old - known as The Duck in recent days.
However, Chelsea have stern competition to land the young forward - with three other colossuses of the world game also looking to tie up Pato's future.
All the interested parties have representatives in Canada for the World Under 20 Championship - where Pato is currently starring.
The Internacional ace fired two goals in Brazil's opening 3-2 win over South Korea and is being tipped as one of the tournament's stars.
His excellent form has only confirmed his prodigious talent to his suitors, and according to his agent, bids have already been made.
"Real Madrid, Inter, Milan and Chelsea have already made official offers for Pato," his agent Gilmar Veloz confirmed.
"We are analysing the deals and will sit down with Internacional. Then at the end of the year his future will be defined."
Chelsea are understood to have made the best offer, with a bid in the region of €20million (£9.9million).
Indeed some sources are suggesting that Veloz is, or soon will be, travelling to England with the player's father to finalise a deal with Chelsea.
Veloz hinted that Chelsea are leading the chase, by admitting Pato may find it difficult to land a work-permit in England.
"With Anderson, he obtained his permit to Manchester United with the condition that he was a talent of outstanding quality - and I don't know if Pato would be treated like this.
"Although, we have not decided whether he would go to Chelsea, Milan, Inter or Real Madrid."
No matter which club sign Pato, he will not be moving until the end of the year as he does not turn 18 until later this year.
"Pato is not yet 18-years-old. To move, he needs to be of legal age, and he is not until September," explained Internacional president Vitorio Piffero
"There is no reason for him to go now. What would he do in Europe until September? As he could not play."
