Celta Vigo star Theo Bongonda admits he'd welcome an approach from Manchester United or Chelsea.

The Belgium under-21 international is on the brink of breaking into Roberto Martinez's senior international squad - just two years after leaving his homeland for Spain.

"I could comfortably stay another two or three years with Vigo, but it is not my ambition to spend the rest of my career with them," he said.

"If Chelsea, Manchester United or Atletico Madrid call me in the near future I should be ready to make the step up to join them.

"Every footballer wants to play at the highest possible level."
