This has all gone a little flat since those West Ham subs. Still David Moyes will be delighted if his team travel back to England with a two-goal lead.
Emile Smith Rowe's free-kick is curled in towards Takehiro Tomiyasu but he's penalised for a shove in the box.
A roar goes up by the home fans as Sporting immediately look to go on the attack.
SUBSTITUTION
Sporting Lisbon 2-2 Arsenal
Goalscorer Paulinho is off but Sporting have exciting teenager Youssef Chermiti coming on.
Someone for Arsenal to be wary of.
