I'd suggest that 'lost yard of pace' would be no different to any other 28 year old. Having said that, does this lost yard of pace now put him behind or in front of Aguero, B Silva, D Silva, Fernandinho, KDB & Jesus in the 'Like shit off a hot shovel' speed stakes?
Outside of the last 12 months at Arsenal can you offer up any other instances of Sanchez's bad attitude? Is he the only star player in recent history to become frustrated at Arsenal's inability to sustain a challenge for major trophies (Henry, Vieira, Fabregas, Gallas, RVP, Nasri)?
I agree about the attitude issue - not a concern for me, but I didn't understand your first line.
How and why are you grouping Aguero, B&D Silva, Fernandinho, KDB & Jesus together in this speed stake argument? I don't get where you are going with this.
Sanchez was a wide forward with great power, and technique. If he loses speed, it's a big deal for a wide forward. David Silva takes a ball, controls it instantly and weaves magic. Totally different game. He's tenacious and got such great touch, but a totally different player who is not going to be so affected by age - at least I hope not.
David White is a poor man's Alexis Sanchez. Similar in physique but not got the same technique, but if you took away Whitey's speed you'd take away half his effectiveness. You take away Sanchez's edge he ends up reinventing himself as midfielder and that's what he's doing now. Still a good player, but no longer elite. If we buy him, we'll be buying a lesser player than the one which graced the Udinese, Barcelona and Arsenal shirt, and he's a player we no longer need.
Gabriel Jesus and Alexis Sanchez. I know who I would play up front. Would you ever pick Sanchez ahead of Jesus? And if you think about this question, think about the players as they are now, not who they once were. That is what, if I can say so with respect, a lot of fans are doing in this thread, they think of Sanchez as the player who destroyed defences over the years but players do age, and we aren't dealing with that player any more. If I am wrong, then between now and the transfer window we should see some evidence of it in terms of goals and assists.
