Arsene Wenger believes that playing Alexis Sanchez day in and day out will not have any bearing on his fitness and that the Chilean is not feeling any fatigue thus far.

The former Barcelona man has played in almost every game that the Gunners have participated this season but is not showing any signs of fatigue, something which is unprecedented for any player at his level. Sanchez has played five games in less than two weeks over the Christmas period but his industry and work ethic against Hull City in the third round of the FA Cup has earned him a lot of admirers.

Sanchez scored the winner against the previous year's runners up on Sunday as the Gunners breezed to a 2-0 win over Steve Bruce's men, who were unable to exact revenge for their loss in the final at Wembley last season.

Wenger revealed that he was tempted to rest Sanchez for the game but with Danny Welbeck and Olivier Giroud unavailable, he did not want to take a chance. Joel Campbell also started for the Gunners alongside Theo Walcott, who made his much anticipated return to first team action after a year in the sidelines.

"He always looked dangerous. He took the corner, he scored a goal and he gave a good chance to Oxlade-Chamberlain. He's lively and always dangerous with his change of direction, his incisiveness and how penetrative he is," Wenger told www.arsenal.com.

"He's interesting to watch because he has a good fighting spirit. He has a good combination of what you want to see from top players - that means that he is ready for a fight and also has talent.

"I was tempted [to rest Sanchez]. Giroud was still suspended today and I knew that it was an important game for us. In the end, he always feels ready.

"I hope [he can keep his energy up for the rest of the season]. There's no reason. You look at the players who have that confidence - you're torn between the fact that when the player's confident and keeping him playing, and giving him a rest.

"I feel that when the players are confident it's important to keep them going, especially when they have that physical potential. He recovers very quickly and we'll see. At the moment he doesn't look in our tests like he has any fatigue problem," he concluded.
