The Man Utd coach is losing patience with his players and admits nobody in the league concedes goals like them.
It was another poor showing for the team as they were defeated by Man United in a game that was sealed by a stunning free-kick by the Portuguese star.
In an away game for the third time this season, the Canaries scored more than one goal as they created chances throughout the afternoon. On the stroke of half-time, Dowell headed Pukki's cross past de Gea, and seven minutes into the second period, he beat the trap to level the game.
If you look at the two goals we conceded, especially the first one, we had the ball on the sideline but we were not physical enough. We have to be more aggressive when there is body contact.
It was too easy for me, and we are the only team in the league who concedes goals like that.
He said that they should have defended in a smarter way and not allowed them to have two or three transitional moments. The first goal we conceded could have been avoided if we had scored earlier. We could have conceded a goal earlier than that, which is why I am not really happy with our performance when we were not in possession of the ball.
The hosts were back in contention to finish fourth after the 25-yard thunderbolt free-kick winner byRonaldo. They are three points behind fourth-place Spurs.

How many games we have played since I arrived, how many were 2-0 up and only got a point? This is six, eight points that we should have had more. This brings us back to the same situation that we didn't defend well enough in. If it wasn't for David de Gea's brilliant save, we would have lost the game and it would have been worse.
If you want to defend properly in this league, you have to be physical, you shouldn't allow them to go past us and through our lines like that. We are still in the race, but we should have had eight points more because this team does not do well enough.
The opposition will be tougher for Manchester United next when they travel to take on the Reds on Tuesday at 8pm on Sky Sports.
The team could be in for a long night if they repeat their performance from the previous game.
Everyone has seen the game today.
They won against Man City and are in the FA Cup final. They have a chance to win four trophies this season.
If we play like we played today, it will be very difficult to get even a point out of this game and this is what we have to be aware of.
We need to raise our level and standard. Fred and Scott will probably not be back, and Raphael Varane will also be a tight race for the game on Tuesday. He hasn't trained with the team.
We have to be aware that the players that we had available today, we will drive to the game and get something out of it.
We need three points. It has happened before in football.
We have to be realistic, we have to play a lot better if they are in possession of the ball.
It is not right to target individuals after Paul Pogba was booed off the pitch by some Manchester United supporters.
The result of the game, a hat-trick by CristianoRonaldo, gave United hope of a top-four finish, but the home fans were not happy with the performance.
Juan Mata replaced Paul Pogba in the 74th minute after the Frenchman failed to make an impact against the bottom side.

The United player was jeered as he made his way off the pitch and then cupping his ears to a critical corner as he went down the tunnel.
Although he admits he didn't hear the boos from the disgruntled supporters, he insists he doesn't agree with their actions.
I can empathise with fans who are frustrated and disappointed. All the time, things have been peaceful.
I don't think it makes sense to target any individual person or player because it's a collective responsibility.
