Former Arsenal striker Thierry Henry was left fuming after Alexis Sanchez's sending off for Inter Milan against Liverpool.
The Chilean was shown a second yellow card by referee Antonio Mateu Lahoz, just moments after a stunning strike from Lautaro Martinez had given Inter hope of taking the game to extra-time.
Sanchez's foul on Fabinho came after an earlier high challenge on Thiago Alcantara which some believed could have been a straight red, but was only deemed a yellow by the official.
However, Lahoz gave a second yellow for the challenge on Fabinho - despite Sanchez getting the ball first and making little contact with the Brazilian.
The the controversial second booking made it harder for Simone Inzaghi's side to deliver the second goal they needed at Anfield and while Liverpool missed chances to extend their lead both before and after the dismissal, the two goals they scored at the San Siro in the first leg were enough to take them through to the quarter-finals.

“I want to talk about the second yellow of Sanchez,” Henry told CBS Sports' Golazo Show, for whom he was working as a pundit.
“If you have played football, you know that’s never a yellow.
“The first one (on Thiago), with the new rules that we have seen, is late. Way late. Foot on the knee. I could have maybe understood if it could have been an orange-red.
“But that second yellow, if you have played football. What is he supposed to do?" the Frenchman continued. "Obviously, your foot is going to go up because you are kicking the ball away.
"We have seen the play here. Full speed. You don’t have time to take your leg away by kicking the ball, it’s impossible.”
BT Sport pundit Fara Williams gave a similar take, saying "There's no way [Sanchez] can stop his momentum as he's made that poke".
"What you can clearly see is he's tried to pull his leg out, and so if you see with the bent knee, I don't think there's force in trying to endanger the player," former England international Williams added.
Her fellow pundit Rio Ferdinand agreed, but suggested Sanchez was "stupid" for giving the referee a decision to make.
Despite the elimination, Inter manager Simone Inzaghi wasn't as upset with the Anfield display as he was with the outcome in the first leg.
"I'm more bitter about the outcome in the San Siro than what happened tonight," the Italian said.
"We played against perhaps the strongest team in Europe at this time and we were their equals. We paid a high price for the red card."
Inter are still very much in contention to retain the title they won last season under Inzaghi's predecessor Antonio Conte, sitting two points behind neighbours AC Milan with a game in hand over the Rossoneri.
