Arsenal boss Arsene Wenger has revealed the surprising reason why he failed to substitute talisman Alexis Sanchez during his side's comfortable Champions League victory against Dinamo Zagreb last night.
As reported by talkSPORT, Wenger has insisted that a break actually makes the Chile international 'tired'.
Sanchez netted a brace in last night's 3-0 triumph for Arsenal, leaving the Gunners with a chance of securing their place in the Round of 16 of Europe's elite competition.

A 2-0 victory in Greece against Olympiakos in two weeks time will ensure the north London outfit's place in the next round of the tournament.
One thing is for sure, they will need Sanchez to be at his sublime best against their Greek counterparts, but it appears that the former Barcelona man isn't in need of a rest.
When asked why he didn't take off the Chilean, the Gunners chief brilliantly responded by saying: "Because a break makes him tired.
"I would have loved to have done it in this game, but when you're 3-0 ahead you're not in a position where you need him to work back.
"We put him central up front where he could spare some energy. It's not like the flank where he has to go up and down. I tried to compromise a little bit, rest him a little bit."
Wenger went on to admit that injuries to Olivier Giroud and Hector Bellerin also played a part in his decision to keep Sanchez on the pitch for the entire game.
Wenger went on to say: "Olivier Giroud had a little problem on his ankle over the weekend so I decided to give him a little breather.
"I took Hector Bellerin off because he had a groin problem just before. Then of course I couldn't take Sanchez off. We now have five days to recover anyway.
"I don't know how important Alexis is percentage-wise, he's just a very important player."
Sanchez is key
Wenger will be well aware that Sanchez will have a huge role to play throughout the course of the season. With the Gunners very much in the Premier League title race, the former Barcelona man has the attributes to lead the club to success this term.
Despite Mesut Ozil's wonderful form in north London, Sanchez remains the club's most important player. Direct, powerful and ruthless, the dynamic forward could yet inspire Arsenal to something special.
