Nicolas Pepe has not set the Premier League alight, in fact, he has largely been anonymous but the argument is that it is far too early to judge him, a point of view I wholly agree with.
In contrast, you have David Luiz, who has been at Arsenal the same length of time as Pepe in terms of games and yet not too many are saying it is too early to judge him.
There is a huge difference in circumstances between the two new signings, Pepe arrived without a pre-season, unfit and without any experience of Premier League football. Luiz, on the other hand, has immense Premier League experience, had a pre-season and was fit.
Luiz came with a reputation of being error-prone and a bit of a clown but his supporters claimed his experience and skill level was such that he would bring calmness to a chaotic Arsenal defence.
Well, we all now know that the Brazilian has lived up to the negative side of his reputation and he has done it in style and the reason that it is not too early to brand him a flop is that none of what he has done has come as any sort of surprise.
He has not brought calmness to the defence and there is little chance he will, he is playing how many of us expected him to, he has not let his detractors down in that sense.
To expect Luiz to be some sort of stabilising force enacting leadership qualities was always fanciful, he has never done neither and yet at 32-years-old some obviously thought that he would all of a sudden turn into some sort of Franz Beckenbauer for Arsenal.
Not only is it not too early to judge Luiz, but he could also have been judged before he signed for Arsenal and that is what makes his signing all the more foolhardy and ridiculous.
He is clearly a flop and it is not going to get any better.
