THAT'S IT! A deserving victory for ATK after a scintillating second-half performance. Balwant Singh's opener was neutralised by Mason Robertson. But Manuel Lanzarote scored a world-class goal off the volley to give ATK the lead again. Everton Santos then doubled that with his first touch on the pitch. Real Kashmir tried until the very end to come back but they ran out of time. It's ATK into the quarters and they will take on Delhi Dynamos. That's it from us here.

83' GOOOOOOOOOAAAAAAAAAAAAAALLLLLLLL! THAT DOES IT! Everton Santos, the substitute, makes immediate impact. Loveday fails to clear it. Everton chests it down and strikes it on the turn into the bottom-right corner, which kisses the post and rolls in.
79' BRILLLLLLLLL! LAAAAAANZZZAAAAAAAA! ATK take the lead again! Lanzarote waits outside the box for Garcia's corner and the winger plays it accurately. What's more delightful is Lanzarote's volleyed attempt, which rises and then drops at the back of the net. Amazing!
72' Another free-kick for ATK around the same region. This time it's Balwant who goes down. Manuel Lanzarote delivers the ball to the centre only to be cleared away by RKFC.
70' A free-kick for ATK at the edge of the box, on the left with Edu Garcia going down to a challenge by Aaron Katebe. He himself steps up to take it and wastes the opportunity with a shot that rolls over the bar.
58' A decent delivery by Bazie Armand from the left for Mason Robertson at the far post. But Robertson doesn't have enough time to step back and play it to the centre.
55' ATK threaten with Manuel Lanzarote floating a cross from the right to Balwant. But Bilal Khan gets his hands on it and punches it away without taking any pressure.
It's even-stevens at half-time. Seven shots and six shots respectively for ATK and Real Kashmir. The Kolkata team took the lead from Balwant Singh's header, while Real Kashmir responded in style with Mason Robertson's long-range effort. This all builds up to an exciting second half so don't go anywhere!
45+2' Balwant with some fancy moves inside the Real Kashmir box. He somehow manages to back-heel it to Lanzarote. The Spaniard tries to curl it to the far post but it only goes as far as Bilal Khan, the RKFC goalkeeper. Half-time!
45' Real Kashmir seem to be allowing ATK a bit more space than necessary. Nobody closes down on Edu Garcia, allowing him space for a shot. Fortunately for RKFC, it takes a deflection from Loveday for a corner.
43' Wonderful cross by Edu Garcia to find Balwant inside the box. But the ATK forward, scorer of their goal, looks for another pass inside the box instead of shooting! Real Kashmir's Loveday clears.
31' MAAAAAAAASSSSSSSSSSSOOOOOOOOONNNNN! A peach of a strike by Mason Robertson to score the equaliser. ATK complain about a foul, but Real Kashmir keep going. Abhash Thapa finds Robertson at the centre of the park and with the ATK players distracted, Robertson unleashes one to the bottom-left corner and beats Debjit Majumder with that thunderbolt!
29' TEMPERS FLARE! Lanzarote loses his cool again. He doesn't take kindly to Real Kashmir defender Loveday's push, shove and the foot on the ATK captain.
26' GOOOOOAAAAAAALLLLL! Balwant Singh rarely misses a good aerial chance and with all the space he had there, the ATK striker delivers! It's only his second goal of the season and it's a vital one at that. Manuel Lanzarote is all by himself, managing to stay onside, and plays it to the far post from the right. Balwant has Loveday for company but the ATK striker manages to outwit him to nod home.
23' Manuel Lanzarote is furious with Bazie Armand as the Real Kashmir defender doesn't allow ATK's Pronay Halder to take a quick free-kick. Referee Santhosh Kumar calms him down and play is underway again.
20' STAYING CALM. Real Kashmir are doing much of the attack and are constantly putting Real Kashmir under pressure. Kofi Tetteh zooms into the box and has Andre Bikey for company. The ATK defender does well here and steals possession to save his team from danger.
15' Another penalty denied. Andre Bikey with a clear push inside the box on Real Kashmir's Aaron but the referee is not interested again. Real Kashmir feel undone here.
10' Pronay Halder really reckless there, elbowing Farhan Genie during an aerial duel and earning himself a card. Could have easily been sent off for that challenge alone! Yellow - Pronay Halder (ATK)
8' MISS! Mason Robertson's ball from the right sends Kofi Tetteh on a chase. The Real Kashmir attacker manages to break the offside trap and finds himself in a sweet spot inside the box. But the right-footed effort into the bottom-left corner rolls wide of the target.
4' Mason Robertson aims his throw to the centre of the box and even though Loveday towers over Andre Bikey, the Real Kashmir defender's glance does not challenge Debjit Majumder.
2' CHANCE! Manuel Lanzarote spots the run by Edu Garcia behind the defender and plays it through. Garcia gets into a good position to score but he shoots over the frame! How that early goal could have helped ATK!
