The striker was one of six Colombia players booked in their last-16 tie and he feels his side were being "undermined" by the match official Geiger
Radamel Falcao has accused referee Mark Geiger of showing bias towards England in their win over Colombia in the World Cup last 16 on Tuesday.
The South American side fell behind in their knockout tie against the Three Lions through a second-half penalty and had six players booked over the 120 minutes before losing 4-3 in the shootout.
Colombia conceded 23 fouls as well, 10 fewer than Gareth Southgate's side in a tight encounter, but Falcao believes his team were at a disadvantage because of the United States referee.
