Sampdoria chief Pasquale Sensibile admits big clubs are watching Pedro Obiang.

The young Spanish midfielder has been likened to Real Madrid legend Fernando Hierro and a favourite of Manchester City chiefs Roberto Mancini and Attilio Lombardo.

"Obiang is a mature player, with a great attitude and quality on the field," said Sensibile.

"Yesterday there were scouts watching from some of the biggest clubs in Europe.

"I worry because there's been too much talk about Obiang. He must finish his development with us."
