David O'Leary faces one of the toughest decisions of his short managerial career as he leads Leeds United back to his old hunting ground of Highbury tonight.
The former Arsenal defender will leave one of his three star strikers a disappointed man - but as United set off by train to London today, which one starts on the bench is anybody's guess.
Alan Smith crashed into the reckoning on Saturday after replacing £11m man Robbie Keane in the 65th minute of his side's 2-0 victory over Southampton.
Until Smith was introduced to the fray Leeds were struggling, but the young striker turned the game on its head with his surging runs and a stunning goal.
Smith admitted afterwards: "It would be nice to start against Arsenal, which is a massive game for us. I was so upset when I found out I wasn't starting - it was much worse than when I was waiting to get on for England last week."
Keane could be the man to make way after a largely ineffective showing against the Saints, as Leeds prepare to resume hostilities with the Gunners after their stormy May meeting.
But they may not face Martin Keown, who is still appealing against a suspension for two off-the-ball incidents which ignited Highbury that afternoon.
Keown is expected to sit out the game but Leeds goalkeeper Nigel Martyn believes last year's fireworks have been forgotten and each side will only have the three points on their mind.
"There was a bit of banter when I was with England last week about the how the tackling's going, but that's all it is," Martyn said.
It is a measure of how far Leeds have come during O'Leary's tenure that they are going south aiming for nothing less than victory.
Lucas Radebe, who is still struggling back to full fitness due to his problematic knee, and long-term casualty Michael Bridges, are Leeds' only two definite absentees.
But Martyn's goalkeeping deputy Paul Robinson could also miss out with a heel injury and Australian youngster Danny Milosevic is on standby.
Europe's best-known referee, Pierluigi Collina, has been handed Rangers' potential powderkeg clash with Fenerbahce in Turkey tomorrow night.
The Champions League qualifying tie, which guarantees millions in revenue for the winners, is already embroiled in controversy following the first leg sending off of striker Michael Mols for kicking Fenerbahce defender Samuel Johnson after an off-the-ball clash.
A scoring draw will be enough to send Rangers through while defeat means they must try again in the UEFA Cup.
Meanwhile, chairman David Murray and manager Dick Advocaat confirmed they were interested in buying Sunderland's Don Hutchison.
