Firstly, Matic and Fabregas are a class above Matuidi and Verratti. They didn't 'outplay' Chelsea with 10 men. Chelsea were wining the tie until PSG got a late goal. Chelsea's strategy was to park the bus. Why do you think that we have a poor record against Chelsea despite 'out playing' them. PSG couldn't compete with Barca's midfield as they lost 5-1 on aggregate and were pretty much swept aside by Barcelona. PSG play with 3 central midfielders and they don't play with a no 10. I'd give Matuidi the nod over Coquelin as he's an experienced player that's done it for years, however Verratti isn't in the same League as a player like Özil or even Cazorla. I'd even take Ramsey over him because he's more complete. As well as having a great passing range and defensive ability, he's a better goalscorer than Verratti.
I never said that we've won everything for the past decade. Our first 11 could improve, however there's no doubt that we have great squad depth.
