England took a huge step towards securing qualification for next year’s World Cup with a 2-1 win over Slovakia earlier tonight.
But one of the main talking points after the match involved a clip of Alli reacting angrily to a challenge from Martin Skrtel.
It sparked huge debate on social media and among pundits watching the game as to who it was aimed at.
Judging from the camera angle it looked as though it could have been aimed at the referee.
But England boss Southgate has played down the incident and insisted Alli was showing it jokingly towards his former Tottenham team-mate.

“I’ve not seen it but I’ve been made aware of it,” Southgate said.
“Kyle and Dele were mucking about, and Dele’s made a gesture towards Kyle. I don’t know what the angle of the pitch is. The pair of them have a strange way of communicating, but that’s what they’ve said when it’s been raised.
And Southgate was quick to change the subject to Alli’s performance for England and went on to say it was the best he’s seen the 21-year-old play since he took over as the Three Lions manager.
He added: “Without seeing it, and I’ve literally just gone and asked him quickly… For me, what it does is detract from what was his best performance for us since I’ve been the manager.
“His work without the ball was top drawer, intelligent positions and turning people over.
“He made fantastic runs behind the opposition defence and was a threat. I don’t know what the angle picked up by the camera is, so I don’t know if that is clear. Hopefully we’ll be talking about that.”
