Mikel Arteta discovered that playing your best goalkeeper can be a good idea as his side recovered from cup exits with late win in Lisbon

There was a temptation to fixate on the moment when Arsenal won this game with a goal that could change their season. Mikel Arteta had urged his players not to panic, not to sink away with hopes of a quadruple long gone, and Kai Havertz got the memo. Gabriel Martinelli crossed from the left and, as the ball dropped, Havertz caught the Sporting defence napping at last, controlled with a feathery touch, took a breath and rolled a finish past Rui Silva to give Arsenal victory in the first leg of their Champions League quarter-final.

It had been a slog at Estádio José Alvalade. Arsenal attempted 488 passes and it was not until the first of two added minutes that they made one really count. Before then it was a grind. Arsenal were often constipated in open play. Although they controlled the game, at least until allowing it to become ragged during a fraught finale, there were long spells when the best the Premier League leaders offered was set-piece wrestling. Noni Madueke, mostly ineffective as he deputised for Bukayo Saka on the right wing, curled an early corner against the bar. Viktor Gyökeres was recorded as being on the pitch. Leandro Trossard tried to score from 40 yards. Leandro Trossard did not score from 40 yards.
