Alexis Sanchez - Spotlight on
Sanchez was replaced by Joel Campbell in the 60th minute of the Gunners’ 1-1 draw against Norwich and clutched his hamstring.
The Chilean played the full 90 minutes of Arsenal’s 3-0 Champions League win against Dinamo Zagreb on Tuesday.
Wenger had admitted prior to the game that Sanchez had a hamstring problem.
And Henry thinks Wenger’s decision to start Sanchez was not vindicated.
“Yes, it was difficult to rest him today because you want to win, but I go back to the Zagreb game. With 20 minutes to go at 3-0, you can give him a little rest," Henry told Sky Sports.
"Obviously I would like to think the 14 hours travelling, playing away with Chile for the World Cup in South America, doesn't help.
"Now we can all say the same thing. If he played today and he scored he would have said, 'I was right to play him', but he got an injury so we are obviously going to say he should have rested him."
It is not clear yet how long Sanchez will be out for.
