England's qualification campaign faltered, though Mariner scored in consecutive pool matches against Hungary and Luxembourg – the latter of which would prove to be his 13th and final England goal. By the time he next played for England, he was an Arsenal player, with the Gunners taking him from Ipswich in February 1984 for £150,000. By now Mariner was in his thirties but he still initially performed well for Arsenal, scoring seven times in the final fifteen games of the season. But age was starting to get the better of him; and he scored only nine goals in 41 games in 1984–85.
