Laurent Koscielny ensured Arsenal of a place in the Champions League qualifiers with the only goal in a tight encounter at Newcastle.

The central defender prodded home from close range seven minutes after the break to ensure that the Gunners could not be overhauled by north London rivals Tottenham in the fight for fourth place in the Barclays Premier League.

But the result was in doubt until the final kick of the game, with Tottenham's home win over Sunderland meaning a late equaliser for Alan Pardew's men would have meant Spurs and not the Gunners getting a shot at Europe's premier club competition.

Newcastle had motivation of their own, after owner Mike Ashley's offer of £1million to be shared between the club's non-footballing staff if they ended a difficult campaign with a victory.

But ultimately, a third successive defeat at St James' Park, albeit despite a much-improved display, saw the staff go empty-handed and 38-year-old goalkeeper Steve Harper denied the perfect finish to his long career on Tyneside in front of a crowd of 52,354.
