Arsene Wenger saw his Arsenal side crash out of the Champions League with a 10-2 aggregate drubbing at the hands of Bayern Munich.
Arsenal lost both legs 5-1 as they were dumped out of the competition at the l ast-16 stage for the seventh successive season, heaping further pressure on under-fire boss Wenger.
Here, Press Association Sport looks at some of the Frenchman 's heaviest defeats since taking charge of the Gunners in 1996.
Manchester United 6 Arsenal 1 (Premier League, February 2001)
Dwight Yorke struck three times with Roy Keane and Ole Gunnar Solskjaer also on the scoresheet as United raced into a 5-1 half-time lead after T hierry Henry had briefly drawn Arsenal level. Teddy Sheringham added a late sixth as Sir Alex Ferguson's champions moved 16 points clear at the top of the Premier League.
Tottenham 5 Arsenal 1 (League Cup, January 2008)
As painful as any of the big losses suffered under Wenger, if not more so. Not only were Arsenal humiliated at the home of their arch rivals, but it also cost them a place in the League Cup final. Jermaine Jenas, a Nicklas Bendtner own goal, Robbie Keane, Aaron Lennon and Steed Malbranque were Spurs' goalscorers at White Hart Lane as Juande Ramos' men claimed a 6-2 aggregate win.
Barcelona 4 Arsenal 1 (Champions League, April 2010)
A 2-2 draw in the home leg of the quarter-final had raised Arsenal's hopes, all the more so when Bendtner gave them the lead in the Nou Camp. But Lionel Messi had other ideas and scored four times to see Barca through.
Manchester United 8 Arsenal 2 (Premier League, August 2011)
Wayne Rooney's hat-trick helped United inflict the biggest defeat on Wenger during his Arsenal reign. Ashley Young (two), Danny Welbeck, Nani and Park Ji-sung also got their names on the scoresheet. An understrength Arsenal replied through Theo Walcott and Robin van Persie, but a chastening afternoon w as soured further by the sending-off of Carl Jenkinson.
AC Milan 4 Arsenal 0 (Champions League, February 2012)
One of Wenger's previous Champions League last-16 exits featured a hefty loss at San Siro after Kevin-Prince Boateng's opener, Robinho's double and a Zlatan Ibrahimovic penalty. Arsenal dug deep to win the return leg 3-0 but it was not enough to turn the tie around.
Liverpool 5 Arsenal 1 (Premier League, February 2014)
Arsenal were swept aside by a rampant Liverpool team, who scored four times in the opening 20 minutes through a Martin Skrtel brace and efforts from Raheem Sterling and Daniel Sturridge. Sterling made it 5-0 at the start of the second half, with Mikel Arteta's penalty nothing more than a consolation.
Chelsea 6 Arsenal 0 (Premier League, March 2014)
Six weeks later, Arsenal suffered an even bigger defeat in Wenger's 1,000th match in charge. Again the Gunners were blown away early on as goals from Samuel Eto'o, Andre Schurrle and Eden Hazard put Chelsea 3-0 up in the opening 17 minutes against an Arsenal side who also lost Kieran Gibbs to an early red card - a case of mistaken identity after Alex Oxlade-Chamberlain handled on the line. The hosts added further goals through an Oscar brace and Mohamed Salah to leave Wenger without a win in 11 attempts against nemesis Jose Mourinho.
Bayern Munich 5 Arsenal 1 (Champions League, November 2015)
Remarkably, the Gunners have now lost their last three Champions League games against Bayern by the same lop-sided scoreline. In last season's group stage, Robert Lewandowski, Thomas Muller and David Alaba gave the German team a 3-0 half-time lead which was soon extended by Arjen Robben. Olivier Giroud pulled one back but Muller had the final word.
