Ajax 0-1 Rosenborg

Ajax had not lost at home for 362 days before Rosenborg snatched victory

Last season's losing finalists Ajax face a challenge to reach the Europa League group stage after a 1-0 home defeat by Norwegian side Rosenborg.

Ajax were beaten by Manchester United in May's final but have since lost manager Peter Bosz to Borussia Dortmund and captain Davy Klaassen to Everton.

Nicklas Bendtner's flick on was missed by Ajax captain Joel Veltman and Samuel Adegbenro ran on to score.

The Dutch side's new boss Marcel Keizer is still looking for his first win.

Ajax were knocked out of the Champions League qualifiers by Nice and lost 2-1 to Heracles Almelo in the opening Eredivisie game of the season.
