Newcastle shocked Arsenal 2-0 in the first leg of their Carabao Cup semi-final at the Emirates on Tuesday evening.
The Gunners dominated much of the clash but the visitors were a constant threat on the break and the in-form Alexander Isak gave them the lead in the first half from Jacob Murphy's pass.
Anthony Gordon doubled the lead in the second half as he pounced first after David Raya saved an Isak effort to give Eddie Howe's side a priceless lead heading into next month's second leg at St James' Park.
