Jose Mourinho has given an astonishing post-match interview, ripping into his own players despite winning the match.
The Benfica boss made four substitutions at half-time of the fourth-round cup game but claimed he should have made nine changes, much was his frustration.
The Portuguese side beat Atletico CP 2-0, scoring both goals in the second half.
Atletico CP are a small team in Lisbon, currently in the third tier of Portuguese football.
Mourinho, who has managed Chelsea, Manchester United and Real Madrid, described his side's first-half performance as "poor"
He said: "And it was poor in the sense that hurts me the most, which is when you're poor in attitude.
"There were many players who weren't serious, who didn't approach things as they should have. At half-time, I made four substitutions, but I would have liked to have made nine.
"At half-time, I identified in the locker room the players I would gladly keep on. There were two who wanted to play. Games are to be taken seriously. The other nine weren't."

The Portuguese manager then told RTP: "In the second half, obviously, we improved a lot. Atlético couldn't get out of their own half as they usually do, get throw-ins, that kid has a fantastic ability to put the ball into the box... It was only a matter of time before we scored."
'If we had scored earlier, the result would certainly have been more decisive. But the attitude in the second half improved, we were completely dominant. I didn't like the first half.
"The attitude was poor. I was calm at half-time, but I was very honest. I said there were things I wouldn't accept.
"I didn't make five changes because I couldn't play 45 minutes without a single substitution. But I made four and I think they changed the game because of the intensity and seriousness."

Benfica sit in third in the Portuguese top-flight league and have a tough trip to face Ajax on Tuesday in the Champions League.
Speaking on his teams form, Mourinho said: "The message is a general message, from Benfica supporters. In my case, I am the Benfica coach and the responsibility is mine, but the players also have one, fundamentally towards Benfica supporters.
"And in terms of attitude, there are things that are non-negotiable and that I cannot accept.
"I am sure that Benfica forgives many things in general, but it does not forgive a lack of attitude."

Mourinho did, however, hold his own hands up. He concluded: "The responsibility lies with the manager, and with me.
"When I criticise the players, I'm criticising myself for not getting the best out of them.
"That's implicit. When I criticise the team and the players, I'm criticising myself."
Since Mourinho took charge in September, after being dismissed by Fenerbahce, the club have lost all four of their Champions League games so far and sit second bottom in the group stage table.
