Why? We have a team that in 5 years time with no investment in transfers will be better than it is now. Don't look at Villa, look at us instead.
Robles - 30y/o
Baines - Replaced by Garbutt
Stones - 26y/o
Jags - Replaced by Browning / Galloway
Coleman - 31y/o
Barkley - 26y/o
McCarthy - 29y/o
Besic - 26y/o
Deulofeu - 26y/o
Rom - 27y/o
Mirallas - Replaced by Henen
Even if Henen, Browning, Garbutt or Galloway don't work out we could still sell a player like Barkley or Rom and buy a cheaper striker and a replacement for any of them.
If any of those players leave their transfer would more than cover their replacement.
In 5 years without any investment we would have a better side than the one today. That's the reason the time is right to build the stadium. Squad players have always been cheap or frees for us.
