(CNN) -- Alex Ferguson's 1500th and final game in charge of Manchester United ended with a freak 5-5 draw at West Bromwich Albion Sunday while Arsenal claimed the final Champions League place on the last day of the English Premier League season.
Ferguson's farewell looked to end in customary winning fashion as the new champions led 3-0 and 5-2 at the Hawthorns until the home side hit back with three late goals in five minutes, Romelu Lukaku equalizing to complete his hat-trick.
It is the first time in the history of the EPL that two sides had shared 10 goals in a match.
It also marks the end of an era with the 71-year-old Ferguson ending his 26 year reign at Old Trafford with 38 trophies, including 13 EPL titles.
Paul Scholes, so influential for United in their prolonged triumphs under the Scot, joined him in retirement. The 38-year-old midfielder came on as a substitute in the 69th minute, shortly before WBA's extraordinary comeback.
It was a day marked by other farewells as Liverpool stalwart Jamie Carragher and his former club and England teammate Michael Owen, now with Stoke, ended their playing careers.
Chelsea interim manager Rafael Benitez also took charge of the Blues for the final time, seeing Fernando Torres score the crucial goal in a 2-1 win over Everton which finally sealed third spot ahead of Arsenal.
It was also David Moyes' last game in charge of Everton before he takes over from Ferguson at United.
With relegation matters settled by Arsenal's 4-1 defeat to condemn Wigan to the drop in midweek, Arsene Wenger's team needed to win at Newcastle to deny North London rivals the coveted fourth spot.
A goal from French defender Laurent Koscielny just after halftime proved enough despite some nervy late moments.
The anxiety increased as news came from White Hart Lane that another Gareth Bale wonder strike had given Tottenham a late 1-0 lead against 10-man Sunderland, who had David Vaughan sent off.
But Arsenal, who mounted an impressive late season charge, were left to celebrate a 17th straight year in Europe's premier club competition.
"The players are special. I've told them many times but they've shown it in the last two months they've been absolutely exceptional," Wenger told Sky Sports.
Tottenham must contemplate the Europa League again after finishing one point adrift.
It was cruel for manager Andre Villas-Boas, his side achieving the highest points tally with 72 of a side not qualifying for the Champions League.
"It is difficult to take, in the end we did what we had to but Arsenal did their job well and go through. It is difficult at this moment," he told Sky Sports.
Manchester City, without a manager after dispensing with Roberto Mancini, slumped to a 3-2 home defeat to Norwich, but had already clinched second spot.
Stoke, with Owen coming on for 16 minutes, drew 1-1 with Southampton while FA Cup winners Wigan drew 2-2 with Aston Villa.
Reading, relegated with Wigan and QPR, lost 4-2 at West Ham and Fulham won 3-0 at League Cup winners Swansea.
Carragher hit the post but Liverpool saw off QPR 1-0 at Anfield with Philippe Coutinho scoring the only goal.
