MILLWALL will make a formal complaint to the FA about West Ham's controversial winner at Upton Park on Saturday.
The Lions felt goalkeeper David Forde was fouled by Hammers midfielder Julian Faubert in the build-up to Winston Reid's second-half strike.
And the South London Press, quoting chief executive Andy Ambler, reports the club will write to the game's head of refereeing to make their feelings known about the incident.
Speaking after the game, boss Kenny Jackett said: "The second goal was a foul on Forde.
"I’ve seen the replay and he [Faubert] has taken his legs away. The referee should have given a free-kick."
