Social media was fired up throughout the game as users were unable to believe what they were watching.
But Kane was to be England's saviour, securing the win with his magic touch.
The winning header came as the clock had just ticked over into injury time. Standing alone at the far post, Kane guided a Harry Maguire header into the Tunisian net.
Kane first scored for England in the 11th minute before Tunisia's Ferjani Sassi equalised in the 35th from a penalty kick.
His winner came at the end of a second half during which Tunisia defended deep and nullified England's attacking intent.
The late winner would have brought a huge collective sigh of relief and English pub owners will now be in for a busy night.
