Virgil van Dijk has claimed referee Tony Harrington appeared nervous during Liverpool's 2-2 draw with Fulham on Saturday.
After Andreas Pereira fired the visitors into an early lead at Anfield, the Reds were dealt another blow when Andy Robertson saw red just 17 minutes in.
Liverpool ultimately recovered to secure a point and extend their lead at the top of the table but Van Dijk insisted the two teams were in agreement that Harrington had not been at his best.
'A great comeback is very positive. It's disappointing having 10 men but we showed fight, kept trying to create chances.
