Chelsea boss Jose Mourinho is chasing Sporting Lisbon superkid Bruma. Mourinho is a big fan of his fellow Portuguese and has followed his progress in the U20 World Cup.

Bruma has a year to run on his deal and unhappy with new terms offered by Sporting's board. The winger is regarded the best to come through the Lisbon club since Cristiano Ronaldo.

Bruma's older brother, Mesca, is currently with Fulham, but was first brought to England by Chelsea, where he spent time in the club's youth system.

"The fact that big clubs are interested in our players means we have good players and this is always important to us," said Sporting president Bruno de Carvalho.
