Teenager Kenan Yıldız came off the bench to help Juventus salvage a 4-4 draw at Inter Milan in a highly entertaining Derby d’Italia on Sunday.

Yıldız was brought on in the 61st minute with the score at 4-2 and Inter seemingly headed for an important victory before the 19-year-old’s late double.

Inter remained second — four points behind Serie A leader Napoli , and one point ahead of Juventus.

Nicknamed “Italy’s derby,” matches between Inter and Juventus are always huge fixtures in the Serie A calendar and the two teams are considered the main title contenders, along with Napoli.

Inter took the lead in the 15th minute when Piotr Zieliński struck a penalty straight down the middle after Marcus Thuram had been fouled by Danilo.

The Nerazzurri had conceded just two goals in its past four matches but they let in as many in six minutes as their defense was caught napping.

First, Juan Cabal floated a delightful ball over the top for Weston McKennie to cushion across to Dusan Vlahovic, who tapped it in from point-blank range.

Shortly afterward, Francisco Conceição dribbled down the right and got past Henrikh Mkhitaryan all too easily before rolling across for Tim Weah to slot home from right in front of goal as Juventus took a 2-1 lead.

Mkhitaryan atoned for his error with a wonderful equalizer in the 35th minute, playing a one-two with Thuram and feinting past a Juventus defender before firing into the bottom left corner.

Inter turned the match around completely two minutes later with another penalty after Pierre Kalulu clattered into the back of Denzel Dumfries. Juventus goalkeeper Michele Di Gregorio got a hand to Zieliński’s kick but couldn’t prevent it going into the bottom left corner.

Inter extended its lead eight minutes into the second half. Danilo tried to head a corner clear but it came to Dumfries who drilled it into the far bottom corner.

The home side came close several times to extending its advantage before Juventus got back into the match in the 71st. McKennie picked out Yıldız, who was unmarked in lots of space on the left, and he surged downfield before firing across into the bottom right corner.

And the Nerazzurri were to regret their missed chances as Yıldız doubled his tally eight minutes from time when he powerfully fired home Conceição’s cross.

Genoa director Marco Ottolini said Mario Balotelli will sign on Monday “barring surprises” and the team desperately needs the former Inter and Manchester City forward.

Genoa had just two shots on target in a 3-0 loss at Lazio as it fell to its fifth defeat in six matches.

Parma came back to draw 1-1 against Empoli and could have won the match late on but Ange-Yoan Bonny sent a penalty onto the crossbar, two minutes after Gabriel Charpentier had leveled.

Monza twice fought back to salvage a 2-2 draw with Venezia.

Roma was playing at Fiorentina later Sunday.
