"Yesterday (Wednesday), I started to train on clay at the Manacor tennis club (in Mallorca), to prepare myself for the Monte-Carlo and Barcelona tournaments," Nadal posted on his Facebook page.

The Spaniard had to pull out of the Miami Masters before his scheduled semi-final against Andy Murray on March 30.

He will be looking to win the Monte-Carlo Masters for an eighth successive year when the event starts on Sunday.

Nadal has also won the Barcelona event in six of the last seven years.

The Barcelona Open will run from April 23-29.
