Firstly, he's out of contract next summer and is currently the highest paid goalkeeper in the world by far despite clearly being a million miles away from being the best goalkeeper in the league, let alone the world. So putting "De Gea chat on hold for at least 2 years" is completely insane.
Secondly, suggesting you'd essentially sign 4 or 5 players to all play one position before a new goalkeeper is actually even more insane.
I've deleted the car comparison from the quoted reply because I can't be arsed delving into yet another level of insanity but if you think the goalkeepers importance to the team is akin to a sat-nav system in a car then to put it in the mildest possible terms; you're significantly underrating the importance a proper goalkeeper has on his team.
We are not just going to let De Gea go on a free to then need to find a £70m+ goalkeeper to replace him. That's not a good use of resources and not every £70m goalkeeper even works out so that could easily jump up that cost.
I'm sure we'll agree a contract with De Gea that balances the risk to reward here and his age, but neither of us need to be concerned about his pay cheque. Either way he has earned it.
Those stats on here show he is the best shot stopper out of the top 6 and frankly that is a pretty significant factor. For example failing to be good in the air at catching, but instead saving a shot after that is the same end result.
Goalkeepers distribution is over rated. You won't get a goalkeeper racking up 30 assists a season. There is only a marginal gain from a great distributor versus passing to a defender who then does the passing. Even that gain is debatable as passing to a CB gains yards in itself which then opens up a longer range for any long passes. Plus either way we aren't Bolton!
4 or 5 players in the same position is not insane. 2 or 3 of those can play at any time and if you have injuries you are then relying on the backups. Those backups have been shown to be poor and can significantly reduce the quality of our midfield engine.
I'm certain the material gain on never using McFred again will be more than any gain on an improvement over De Gea. Take into account the better our midfield is the more control of the game we have, the more chances we create, the more goals we score and the less defensive actions we are likely to concede thus less need for the goalkeeper to be involved.
Same principles apply in most positions. If you can remember back to SAF days our goalkeepers could go most games with very little involvement. Their key skill required was thus to be alert when called on once or twice a game. De Gea is one of the best in the business for this. He might not rush out and be a sweeper keeper, but it doesn't matter because he'll save the shot and likely rebounds as well.
The obsession with the modern keeper is insane!
