Kassai dismissed Arturo Vidal for a very harsh second yellow card with just minutes of the game remaining while his assistants wrongfully allowed two of Cristiano Ronaldo's goals to stand despite both clearly being scored from offside positions.
And Lewandowski, who scored from the spot to give Bayern Munich the lead on the night before they eventually fell to defeat on the night to crash out of the tournament, believes officiating decisions cost his side dearly.

1/22 Keylor Navas – 6 out of 10
Found wanting when called upon. Should have done better to prevent Ramos’ own goal.
2/22 Dani Carvajal – 7 out of 10
His early effort from range may not have gone in but it set the tone for Madrid to have the better of the first half.
3/22 Nacho – 7 out of 10
More solid than his defensive partner, and looks to be benefitting from gaining Zinedine Zidane's confidence.
4/22 Sergio Ramos – 6 out of 10
Unfortunate to divert the ball into his own net, but it could have been avoided with a little more communication.
5/22 Marcelo – 9 out of 10
Excellent. Superbly blocked Thiago’s effort early on, then produced a brilliant goal-line clearance after the break to deny Robben. Impressed going forward too, setting up Ronaldo in extra time.
6/22 Luka Modric – 7 out of 10
Key to Madrid’s excellent spells of first half build-up. Ronaldo should have rewarded one particularly special pass with the goal it deserved.
7/22 Casemiro – 7 out of 10
Careless in his challenge on Robben for the penalty. Otherwise, a solid presence disrupting Bayern’s forays forward.
8/22 Toni Kroos – 5 out of 10
Struggled to match the influence of his fellow midfielder Modric.
9/22 Isco – 6 out of 10
Failed to build on Saturday’s excellent showing at Sporting.
10/22 Karim Benzema – 5 out of 10
Offered very little before being hauled off for the more impactful Asensio.
11/22 Cristiano Ronaldo – 8 out of 10
A quiet start but then came another ‘clutch’ goal, just like his two in Bavaria. Two more followed thanks to poor officiating, but this was still a reminder that you should never write Ronaldo off.
12/22 Manuel Neuer – 6 out of 10
Will be disappointed to have conceded six over the two legs, but was outdone by some poor officiating here.
13/22 Philip Lahm – 6 out of 10
Struggled to cope with Marcelo, who got the better of him too often. We have come to expect more.
14/22 Jerome Boateng – 7 out of 10
Heroic block on the line stopped Ramos from putting the hosts in front in the first half.
15/22 Mats Hummels – 8 out of 10
Another defender who put his body on the line when it counted. Spectacularly blocked Kroos’ shot in the first half.
16/22 David Alaba – 5 out of 10
His poor crossing let his teammates down when they were making headway early on.
17/22 Xabi Alonso – 5 out of 10
Surprisingly poor in possession during his last Champions League appearance, with several wayward passes. Replaced by Thomas Muller deep into the second half.
18/22 Arjen Robben – 8 out of 10
Made things tick in Bayern’s attack. Questionable role in the penalty, maybe, but his side's stand-out performer still.
19/22 Arturo Vidal – 4 out of 10
His tackle was fair and should not have resulted in a red, but still, too often a liability. Should also have done better when slipped in by Robben soon after Bayern’s first goal.
20/22 Thiago – 5 out of 10
Off the pace in the opening stages and failed to grow into the game.
21/22 Franck Ribery – 5 out of 10
A fading force, unfortunately. Simply did not trouble Madrid’s backline with the regularity of Robben. Withdrawn for Diego Costa.
22/22 Robert Lewandowski – 6 out of 10
Not his best night, despite cooly converting the penalty.
"In the game today I think we could have won and played the next round but the referee made a lot of errors," he said after the game. "I think it was impossible to play Real Madrid with 10 men.
"It was not a red card, and for their goals it was offside for one, maybe two. Also, for my situation as well, when I was one-on-one, I was not offside either.
"It's very difficult to play against Madrid at the Bernabeu if you have a situation like today.
"Yes [it's frustrating] because when you know you are so close to playing in the next round, but it is not your decision that is happening on the pitch. After one one decision they scored a goal and one was offside. It's very difficult because you can fight and play well but sometimes it's impossible to win or play in the next round.
"Of course, after the 90 minutes we had won the game 2-1 and had a good chance but with 10 men for 30 minutes it's very difficult to play Real Madrid and that's why we are not in the next round."Reuse content
