The Chilean international has been one of the Premier League’s standout players this season, with 13 goals and seven assists in 25 league appearances.
His form in North London has prompted a number of observers and pundits to label him one of the best buys of the season, and certainly the Gunners’ star performer.
However, since the turn of the year, Sanchez has netted just four goals and only one in his last 11 games in all competitions.
While his goal scoring struggles haven’t affected his team’s excellent form of late, it’s still quite surprising to see him tail off in front of goal in such fashion, and Wenger concedes he could be in need of a break.
“He's a bit fatigued and in a position where he has scored less,” Wenger was quoted as saying by the Daily Mail.
“He wants to force his game and then is more involved in physical battles. Maybe goalscoring is on his mind, so he wants to do too much and he wants to force his game.
“I'm tempted to give him a break at some stage. I have been for a long time. It's not that he won't let me, I will decide that. It's just that every game now is so important, you always have a hesitation to do it.”
Should Arsene Wenger give Alexis Sanchez a rest?
Now that the Champions League campaign is over, the Gunners’ main focus will be on the FA Cup and the race to finish in the top four of the Premier League.
If there is one thing that Wenger’s side doesn’t lack, it’s great depth of attacking quality - illustrated by their record-high 15 different league goal scorers this season.
A fully fit Sanchez will be vital for a possible FA Cup final showdown, as well as that key league encounter against Manchester United in May, therefore a rest is arguably necessary.
In the midst of their end of season run-in they soon come across relatively straightforward fixtures against Burnley and Reading, in the FA Cup semi-final – games which Sanchez can sit out.
However, with fixtures against Chelsea and Liverpool also on the horizon, Wenger will want to make sure he deals with the situation carefully in order to maximise results.
