UPDATE 1-Soccer-Barca's Iniesta suffers thigh injury

(Adds quotes, detail)

MADRID, May 10 (Reuters) - Barcelona midfielder Andres Iniesta will miss the King's Cup final with a thigh muscle tear, the Primera Liga leaders said on Sunday.

The Spain international, who scored the equaliser against Chelsea which put them into the Champions League final, picked up the injury during Barca's 3-3 home draw against Villarreal.

"(Losing Iniesta) is worse news then not being crowned champions," coach Pep Guardiola told reporters.

Iniesta will undergo further tests on Monday when it should become clearer whether he will be fit for the Champions League final against Manchester United on May 27.

Barca play Athletic Bilbao in Wednesday's King's Cup final in Valencia's Mestalla.
