Joao Neves had given Portugal a sixth-minute lead, but it struggled to build on that as Wissa levelled on the stroke of half-time to share the points in Group K.

Portugal made a dream start with Pedro Neto lifting a lovely cross into the box from the left, and Neves rose highest to head across goal and in, dedicating his opener to Diogo Jota.

DR Congo attempted to immediately fight back, with Wissa drilling a low shot wide, while Edo Kayembe's bouncing shot was easily held by Diogo Costa shortly after the half-hour mark.

Though Portugal dominated possession, DR Congo scored the next goal in the fifth minute of first-half stoppage time. After a short corner, Arthur Masuaku whipped a delightful cross into the crowd at the back post, and the unmarked Wissa thumped his header into the roof of the net with the last touch of the half to create history.

Portugal thought it had retaken the lead 10 minutes into the second half when Neves chested down another Bruno Fernandes cross, but Joao Cancelo had drifted offside before his overhead kick hit the back of the net.

Moments later at the other end, Cedric Bakambu pushed his way onto a loose ball to fire against the near post from the right of the box, but he was penalised for a foul in the build-up.

Cristiano Ronaldo poked two half-efforts wide of the post as he fell short of another record, and Bakambu fired wide, but neither side could find one last crucial opening to grab a winner.
