Liverpool may have claimed a major advantage in their UEFA Europa League round-of-16 clash after beating Manchester United 2-0 on Thursday, but manager Jurgen Klopp is afraid referee Carlos Velasco Carballo may yet spoil their party.
The Reds have one foot in the competition's quarter-finals after triumphing in Thursday's first leg, but Klopp is fearful Carballo, whom he sees as too card-happy, could ruin their tournament run, per the Mirror's Alex Richards:
We don't have to criticise the referee because tonight he didn't decide the game.
