EFL fans have been left baffled over Portsmouth’s goalkeeper substitution.

Keeper Nicolas Schmid was forced off after suffering a first half injury.
And he was replaced by deputy Ben Killip, with the pair sharing an embrace as they switched over.
It was an eye-cathcing sub as Schmid and Killip bore a striking similarity with one another.
They both have curly blond hair and beards, prompting confusion for viewers at home.
One reacted saying: “I swear Portsmouth just bought on a stunt double for their keeper. Absolute doppelganger.”
Another added: “Should have just swapped them at half time without anyone knowing.”
A third wrote: “Bit unfair cloning your starting GK, Pompey.”
And another commented: “Had me questioning my sanity.”
The incident took place during Portsmouth’s 0-0 draw with Southampton in the South Coast derby.
Shortly afterwards the match was interrupted by a pitch invader, who made it as far as the halfway line and appeared to gesture towards the away fans.
Saints also aimed a cheeky dig at their rivals by unveiling a provocative tifo before the match, showing James Beattie celebrating a goal against Pompey in 2003.
