Pique left for half-time with neck problem and feeling dizzy

Barcelona suffered against Real Sociedad at the Camp Nou. So much so that after a Real Sociedad corner, Pique suffered a problem which lasted for a few minutes. 

It seems like the way Pique turned his neck when he cleared the ball caused him discomfort in that area and when half-time came along, the defender seemed to struggle to return to the dressing rooms. 

Pique was not 100% at the end of the first 45 and he has suffered the odd problem in several games, but he has always been able to carry on. Despite those things, he is playing very well. 

Nobody warmed up at half-time to replace Pique and he came back out for the second half. Real Sociedad caused Barca plenty of problems in the first half and the Catalans started with Messi and Braithwaite up front.
