Mikel Arteta has hailed the impact of his Arsenal substitutes after Kai Havertz and Gabriel Martinelli combined to secure a dramatic 1-0 victory over Sporting CP. The Gunners looked set for a frustrating night in Lisbon before the duo entered the fray to hand the Premier League side a vital edge in their Champions League quarter-final tie.

Kai Havertz has labelled David Raya as the best goalkeeper in the world after the Spaniard's heroics kept Arsenal alive in their Champions League quarter-final first leg against Sporting CP. Despite Havertz netting a dramatic late winner in Lisbon, the forward insisted that his teammate remains one of the most underrated players in the game.

Havertz is overjoyed after the clash with Sporting Lisbon

Arsenal will take a 1-0 lead into the second leg of their Champions League quarter-final with Sporting CP after prevailing in Lisbon on Tuesday. Kai Havertz came off the bench to score in the last minute of a match that was seriously lacking in quality right until the final knockings, and the Gunners now have one foot in the last four.

The German national team’s attack shines even without (and with) Deniz Undav; Lennart Karl is proving himself worthy of more than just a trial run; the defence is holding its own despite the odd wobble; and Julian Nagelsmann’s measures are paying off.
