I don't think Fernando is as bad as people make out, in that regard. he's no Yaya, but if the whole team is passing the ball well, I don't think he has a problem joining in.
It's usually a team thing, when we go to shit imo, rather than one midfielder.
It almost happened to Yaya last night when he was mugged due to Stones' early passing as if he was wearing rubber clown shoes. Later in the game, when Stones calmed down, it all looked easy.
I thought Fernando looked nervous as hell vs Spurs away. I don't mind him as a player. I just don't think he wants the ball enough and when we're at our best it's been with Toure's nous and passing ability or Fernandinho's energy and willingness to drop very deep then explode forwards with or without the ball.
Fernandinho can brake the press with a burst of speed or a pass. Toure with a turn under pressure or a quick round the corner ball.
I don't think Fernando has ever shown any signs of being able to brake the press and just passes it the way he's facing. He struggled with that at first. He's better now. But if he's the link between back four and front 5. I think the team would end up as a mess and so many players would be out of position due to inferior passing.
Granted Toure may get caught the odd time or Fernandinho may give it away but for me, no where near as often as Fernando with just 'English' it and play the way he's facing.
As you say though, there's certainly a time and a place for him. But not starting for me. Spoiling or closing out a game, sure.
