Who was Dele Alli's obscene gesture aimed at?

England went behind early on in the game but came back to win thanks to goals from Eric Dier and Marcus Rashford.
Alli endured a frustrating evening, looking to be positive but just lacking a touch of finesse at key moments. His frustration was clear when he was caught giving someone 'the finger' in the second half.
The midfielder is thought to have made the gesture at referee Clement Turpin following a robust challenge from Slovakia's Martin Skrtel.
The 21-year-old felt that the official was not affording him sufficient protection and was allowing the Eastern Europeans to get away with an overly-physical approach.
Alli could now face disclinary proceedings.
Speaking after the game England boss Gareth Southgate said "I haven't seen it but I'll deal with it in the next couple of days."
