Xavi’s Barcelona climbed top of La Liga with a 4-0 win over rock bottom Cadiz on Saturday in a match interrupted by a medical emergency in the stands.

Barca have 13 points from five matches. Champions Frenkie de Jong scored first on 55 minutes with Polish striker Robert Lewandowski doubling the advantage ten minutes later. The match was halted in the 82nd minute because of a presumed heart attack in the stands.
