Hmmm. Maybe I have been too harsh on Roy. Perhaps this is why he left making substitutions so late. I agree that PV doesn't have that many options off the bench.

With his subs Vieira simply invites pressure. It was written though, that Conor G. would score the winner.
Another sickening blow after Clyne was carried off after tangling with a player that should not have been on the pitch.

We were set up to defend under Roy which is less tiring than playing football . Maybe PV feels he needs to respond when the other side brings on 3 internationals in one go . Roy just took it as a complement .

That is not true.

You should train to gain fitness for the level and typical of football you are playing.

This has been an issue with Palace for a long time something is not right with the fitness.

A clear example is look at other teams not the big ones who have players which are not at Palace quality level but the work rate is a lot higher.

The other issue is poor tactics/subs or lack off

It's not a lack of fitness. Palace are a fit team. It's purely down to strength and depth of squad.
Look at what Chelsea can throw on the field off the bench.
Most of them would walk straight into a Palace 11 every week.

Viera switched around what he could but it's a very different looking bench compared to the top 6 teams in the country!

Hughes, Tomkins, Mateta and Schlupp can all play football but they are not Mount, Gallagher, Pulisic, Loftus-Cheek or potentially Broja.
We also had Riedewald, Luca, Ebioei, Gordon & Johnstone.
Chelsea still had Bettinelli, Azpilicueta, Chalobah and Koulialy bench-warming!
Palace just don't have the financial clout to be able to afford to have game changing players sitting on the bench they play from the start!

However when you compare Palace's efforts against Chelsea on Saturday to the W*nkers pathetic effort yesterday against City there is no absolutely no comparison given the clubs budgets involved!!!
