MILAN, May 22 (Reuters) - U.S. investment fund Oaktree Capital Management is not planning to sell Inter Milan immediately after it took control of the Italian soccer club following a missed debt payment, a source close to the matter said.

Oaktree will be a "patient investor", the source added.

Earlier on Wednesday the U.S. investment firm said it had taken ownership of Italian soccer champions Inter after a missed 395 million euro ($428 million) payment from the club's Chinese majority shareholder.
