Bukayo Saka’s 12th minute goal put Arsenal ahead in a match that left the English side’s Champions League hopes hanging after they played a 2-2 draw with Bayern Munich in the quarter-final first leg at Emirates Stadium.
Harry Kane also returned to north London with a goal.
Kane, Tottenham’s record goalscorer, received a predictably hostile reception from Arsenal’s supporters.
Bayern belied their poor form in the Bundesliga to turn the game around before the break as former Arsenal forward Serge Gnabry swept home the equaliser six minutes later.
Kane’s moment arrived when William Saliba tripped Leroy Sane at the end of a blistering run after 32 minutes.
The England captain stepped forward for the resulting penalty and silenced the taunts with his 15th goal in 20 appearances against Arsenal.
Mikel Arteta’s side were not at their fluent best but substitute Leandro Trossard was the beneficiary of outstanding work by Gabriel Jesus to equalise.
Arsenal felt they should have had a penalty in the final seconds of stoppage time but the referee waved away their appeals when Saka went down as he was challenged by keeper Manuel Neuer.
The Gunners were arguably also fortunate not to concede a penalty themselves earlier in the half, when Gabriel picked the ball up with his hands after the referee had signalled for a goal-kick to be taken.
Several Bayern players complained at the time but the referee swiftly waved their appeals away.
The second leg in Munich is on Wednesday, 17 April.
Arsenal left the pitch amid a mood of disappointment and frustration after a performance that was unusually tentative.
The Gunners’ late equaliser from Trossard, who has scored six goals as a substitute this season, sets the second leg up perfectly, although Bayern will feel they are favourites at the Allianz Arena.
Bayern Munich are locked in a season of desperate struggle on the home front, with their long-held Bundesliga domination about to be ended by Bayer Leverkusen and coach Thomas Tuchel leaving the club at the end of the campaign.
Kane, inevitably, got on the scoresheet and played some glorious passes, although he was fortunate to escape stronger punishment than just a yellow card after Arsenal defender Gabriel was floored with an elbow in the second half.
