Chelsea relinquished a 1-0 half-time lead to lose 2-1 at Fenerbahce, with the Turkish club proving their presence in the UEFA Champions League quarter-finals was more than justified. Arsenal meanwhile dominated play but were held 1-1 at home by a battling Liverpool outfit, with the return leg at Anfield promising to be a classic.

Arsenal 1-1 Liverpool
Goals: Emmanuel Adebayor (23) for Arsenal, Dirk Kuyt (25) for Liverpool
A solid and organised Liverpool team showed their big-match temperament once more by holding Arsenal to a draw, despite the Londoners having much of the play. Emmanuel Adebayor's headed goal from a corner was no more than Arsenal deserved but the Reds hit back within two minutes to record a precious away goal. The Gunners gave it their all in the second half but the 2005 winners held on in what is the first of three matches in the space of a week between the two teams.

Key man
Steven Gerrard proved he is still the heart and soul of a Liverpool team which comes into its own when the chips are down, and he combines with star striker Fernando Torres as if they had been playing together for years. Gerrard dictates the midfield, picks the lock of opposition defences and is not one to flinch from a tackle. The Liverpool captain never gives in and it was he who picked his team up after Adebayor's opener, providing the cross from which the Reds scored an invaluable away goal to take back to Anfield next week.

The turning point
In the 25th minute, barely 120 seconds after Arsenal had opened the scoring, Gerrard seized on the Gunners' post-goal laxity by feeding Ryan Babel then taking the ball himself down the inside-left channel, dropping the shoulder and slipping the ball invitingly across the box. Dirk Kuyt outran Gael Clichy to slide the ball home and notch his fourth goal of the season in the UEFA Champions League.

Fenerbahce 2-1 Chelsea
Goals: Colin Kazim-Richards (64), Deivid (81) for Fenerbahce, Deivid (13 og) for Chelsea
Fenerbahce once again shocked one of Europe's biggest clubs at home in what has been a memorable Champions League campaign. Visitors Chelsea dominated the first half, seemingly creating more chances in the opening 45 minutes than they had all season in Europe, but the Istanbul outfit weathered the storm and went into the break only one goal adrift. After the interval, Zico's coaching skills made the difference, with former Sheffield United forward Colin Kazim-Richards equalising within nine minutes of coming on as a substitute. Deivid then scored an absolute pearl to give this gutsy and talented Fenerbahce side a well deserved win.

Key man
Brazilian Deivid went from zero to hero in the space of just over an hour. In an attempt to help out his team-mates, he played very deep in the first half, so much so that he ended up diverting a Florent Malouda cross into his own net. He nevertheless shook off this initial disappointment to stamp himself on the game and score the winner with nine minutes to go, firing an incredible shot into Carlo Cudicini's top corner from 25 yards out - the fifth goal of the season in the UEFA Champions League for the former Bordeaux and Sporting Lisbon star.

The turning point
Burly goalkeeper Volkan Demirel (1.91m, 92 kilos) kept his team in the game by pulling off a string of world-class saves in the first half, almost single-handedly keeping Didier Drogba and Co at bay.
