Nacer Chadli opened the scoring inside three minutes only for Adam Johnson to level 90 seconds later.
We dominated the first half, Mousa Dembele struck the woodwork and having gone into half-time level at 1-1, it took just two minutes for Christian Eriksen to restore the lead.
We continued to create chances and hit the woodwork again through Erik Lamela only for Sunderland to level eight minutes from time with a stroke of fortune as Jordi Gomez' free-kick was turned into his own net by Harry Kane.
