Arsenal fans will still be reflecting on their agonising defeat to Sporting Lisbon in the Europa League on Thursday night.
With the aggregate score 2-2 after the first leg in Portugal, the Gunners took the lead through Granit Xhaka's first-half strike. Yet an audacious long-range effort from Pedro Goncalves levelled the tie - forcing extra time and a penalty shootout at the Emirates.
Gabriel Martinelli's missed penalty allowed Nuno Santos to send Sporting through to the quarter-finals. Arsenal will be looking to bounce back from their European exit when they take on Premier League rivals Crystal Palace at home on Sunday afternoon.
