Weak week by Spanish clubs cast La Liga's dominance into question

Four losses, two wins, one draw. It was not a good week for Spanish clubs in European competition. Champions League title holders Barcelona, previously thought to be all but unbeatable, kicked things off with a dispiriting home loss to Rubin Kazan Tuesday. A day later, the Madrid clubs turned in a pair of stinkers; Real played poorly in losing to AC Milan at home and Atletico were trounced 4-0 by Chelsea at Stamford Bridge.
