Nigerian youngster Alex Iwobi was impressive as Arsenal advanced into the quarter-finals of the FA Cup after thumping Hull City 4-0 in their replay on Tuesday night.
The Super Eagles forward was on from the start and was involved in most of Arsenal’s best moves on the night.
Two goals each from Olivier Giroud and Theo Walcott sealed the win for Arsenal.
They will now host Watford in the last eight at the Emirates at the weekend.
Walcott had the ball in the net in third minute but his effort was ruled out for offside.
Joel Campbell had a chance in the 10th minute after being put through by Alex Iwobi only to shoot wide off target.
The game was delayed for some minutes following a clash of heads between Per Mertesacker and Nick Powell.
In the 30th minute, Ospina made a brilliant one hand save that took a slight deflection off an Arsenal defender.
Arsenal made their first substitute in the 32nd minute, bringing on Nacho Monreal for Mertesacker who did not recover from the head injury sustained earlier.
Alex Bruce made a good clearance in the 38th minute, making a timely clearance for a corner off an Arsenal counter.
Olivier Giroud finally opened the scoring in the 41st minute, pouncing on a poor back pass by David Meyler.
Kieran Gibbs almost made it 2-0 in the 43rd minute but his long range strike struck the crossbar.
In the 51st minute Elneny took a fine volley from the edge of the box which was tipped over the bar by Jakupovic.
In the 56th minute, Gabriel came off injured and was replaced by Aaron Ramsey.
Hull came very close to equalising in the 65th minute but Powell’s effort came off Ramsey and went for a corner.
Giroud made it 2-0 in the 72nd minute, tapping in from eight yards Walcott’s cross.
A minute later Jeff Reine-Adelaide replaced Ramsey who went off injured.
Walcott got on the score sheet in the 77th minute to make it 3-0, slipping the ball pass Jakupovic from a Campbell through ball.
Giroud almost grabbed his hat-trick in the 83rd minute but hit a weak shot straight to Jakupovic.
Walcott, off an Iwobi assist, got his brace and Arsenal’s fourth in the 88th minute as his shot took a slight deflection before flying past a stranded Jakupovic.
