Real Madrid's Vinicius Junior scored twice, including an 83rd-minute penalty, to snatch a 2-2 draw at Bayern Munich in an entertaining Champions League semi-final first leg on Tuesday.

The Brazilian struck against the run of play when he slotted in to give the visitors the lead from Toni Kroos' defence-splitting pass after 24 minutes at Allianz Arena.

Bayern struck twice in four second-half minutes to turn the game around, with Leroy Sane threading home a powerful shot in the 53rd minute and Harry Kane edging his side ahead with a penalty soon after.

Madrid, however, earned a spot-kick of their own when Rodrygo was brought down and Vinicius coolly converted it to equalise, leaving this tie wide open ahead of next week's return leg.

Facing each other for a record eighth time at this stage of the competition, it was Bayern who started well, racking up half a dozen attempts on goal by the 15th minute with Sane and Kane coming close.

Madrid needed only one chance to score though, stunning the home crowd when Kroos sliced open the Bayern defence with a through ball and Vinicius chased it down to beat Manuel Neuer.

Kroos almost added another himself in the 51st minute but his curled shot was palmed wide by Neuer. Instead, it was Bayern who scored two minutes later with a solo effort and shot from Sane for a deserved equaliser.

Their comeback was complete in the just four minutes later when Jamal Musiala was brought down by Lucas Vazquez and Kane sent Andriy Lunin the wrong way to put the home side ahead.

Madrid, chasing a 15th European Cup, levelled in the 83rd minute with Vinicius' penalty to set up a mouth-watering return leg in Madrid next week.

The winners will face either Borussia Dortmund or Paris Saint-Germain, who meet in the second semi-final on Wednesday.
