Barcelona forward Pedro has alerted Liverpool and Manchester United after revealing that he is unsure about his future at Camp Nou beyond this season.

The 27-year-old has made only 10 appearances in the league for Luis Enrique's side this term.

The Mirror reported that the Premier League giants Liverpool and United are interested in signing the Spain international.

Pedro will have one year left on his contract in the summer. The 2010 World Cup winner with Spain admitted that he is happy at the Catalan club, but fears that he could be pushed out of Barcelona later this year.

"Every year it's complicated to play here because I'm competing against the best players on the planet. It's difficult to be 100-percent happy, but I feel comfortable here," Pedro told the Spanish publication AS.

"Those who have fewer minutes want to play. I don't know if they'll ask me to leave. I'm happy here and I want to continue but I don't know what might happen tomorrow. We'll talk at the end of the season."

"The players that are here are very important players and they score a lot of goals. I can only work hard and try to help the team.

"We've been working the same as we always do but we're in a good dynamic in terms of results and morale. We are on a good run and we're all in good shape physically. Hopefully we'll have something to show for it at the end of the season," he added.

Barcelona's first choice right-back Dani Alves has less than six months on his contract and is likely to leave Camp Nou in the summer. The La Liga giants are facing a transfer ban and Pedro is expected to feature in the right-back role.

However, the forward admitted that he is not comfortable to play as a defender for Enrique's side.

"I've never played there, although I have played at left back in training for Spain. But I'm a forward. It's difficult to play there because you have to watch your line with the centre backs, defend... It's not my natural position but if they want to convert me I'll be happy to do it," Pedro stressed.
