Portuguese champions are the undisputed favorites in the showdown with Villarreal in Europa League semifinal. However, the statistics leave the Catalan club a substantial chance at least to a draw in the first leg on opponent's field. The case is that Porto has the perfect away record, winning 7 matches out of 7. And at home they twice lose points - in particular, were defeated by Sevilla. Meanwhile, Villarreal won both last guest games in the tournament. So, maybe Yellow Submarine will not be drowned at Porto?
