Havertz scored the winning goal against Sporting in the tie after coming on as a substitute to give Arsenal ​an advantage heading into next week’s return leg in ​London.

“Definitely a big turnaround for us because we lost ⁠the last two matches. So we wanted to get a ​turnaround today, and we made that happen,” the German told ​Amazon Prime.

Arsenal’s ‘quadruple’ hopes have been downgraded to a ‘double’ this season following their defeat by Manchester City in the League Cup final and shock loss to Championship side Southampton in the FA Cup on Saturday.

However, Havertz said ​the north London club can still end the season with trophies.

“We stick ‌together ⁠as a group; we have so much more to come this season. Seven weeks to go, we can win big titles, and we’re going to go for that,” he said.

Havertz was ​also full of ​praise for ⁠goalkeeper David Raya, who was the player of the match in the Champions League tie ​as he was forced into making several crucial ​interventions.

“For me, ⁠the last two seasons, the best keeper in the world. He’s (David Raya) outstanding, he’s saved us so many times, and we’re ⁠very ​glad to have him.”

Arsenal, who are ​top of the standings with 70 points, host Bournemouth in the Premier League ​on Saturday.
