Dele Alli faces the threat of being hit with an international ban after giving a middle-finger salute in England’s 2-1 victory over Slovakia at Wembley that left Gareth Southgate’s team on the brink of qualification for the World Cup.

England fought back from falling behind in just the third minute with goals from Eric Dier and Marcus Rashford, who had been at fault for Slovakia’s opener.

But the victory that means England remain top of Group F, five points ahead of Slovakia, with just two qualifiers remaining, was marred by the actions of Alli.

Following a challenge that went unpunished from Martin Skrtel, Alli was caught by the television cameras sticking his middle finger up, which prompted allegations the gesture was aimed at referee Clement Turpin.
