Spain midfielder Andres Iniesta has a "minor muscle injury", the national team doctor has revealed.

Iniesta brilliantly set up two goals in the opening 15 minutes and was the star performer as Spain dominated the first half of a World Cup warm-up match in which they thrashed Poland 6-0 in Murcia on Tuesday night.

Iniesta was forced off after feeling discomfort in his thigh, but Dr Oscar Celada said: "He didn't notice any tear and it has not got any worse. It was at the start of the match and as he wasn't comfortable, we made the change - it's a minor muscle injury."
