That's just not true at all. We've had one terrible game and the reaction to it on this forum is laughable!
We're an attacking football team who defend from the front, the best way to defend in our set up is to keep the ball and when we lose it by winning it back high up the pitch. We will do this better by having more attackers on the pitch, not more defenders.
There would also have been plenty of games throughout the season, even if Laporte was fit, where Laporte would be rested and we'd play one of these combinations.
Plenty of these combinations are plenty good enough. and we don't have problems defending from set pieces, it's just that Rodri and Laporte fell asleep for the Norwich and Spurs goals respectively from corners. We are absolutely fine at defending set pieces other than that.
Even Pep disagrees with last sentence, he said Rodri will help us defend from set pieces as we are a short team, especially after Kompany retired.
