Soccer star David Beckham (search) suggested he could leave Real Madrid and return to England, having become upset with photographers who take pictures of his young children at school.

Beckham has spent two seasons with Real Madrid (search) but is now reconsidering his future with one of the world's most glamorous soccer clubs.

"I've made people well aware of what I get upset with in Spain is the paparazzi, but I've had a couple of incidents happen in the last two weeks which have really made me sit back and think," Beckham said.

Beckham — the England team captain, fashion icon and marketing giant — joined Real Madrid in a transfer from Manchester United. He lives in the Spanish capital with his wife, Victoria, and their sons, Brooklyn, Romeo and Cruz.

"I believe that when my children go to school or nursery, they should be left alone, but they're not," Beckham said. "And that's become a problem. ... When they are on their own at their school, nursery or football school, then it is crossing the line and I don't know what to do."

Beckham has said he received death threats at Manchester United, and kidnap plots were uncovered in 1999 and 2002 against Victoria, Brooklyn and Romeo.

Real Madrid hasn't won a trophy in Beckham's two seasons, and coach Vanderlei Luxemburgo is under pressure to shake up the team. Luxemburgo has called Beckham the hardest-working player on the team.

"I've always said I love playing for Real Madrid," Beckham said this week. "It's one of the biggest clubs in the world, even though we haven't won anything."
