Alexis Sanchez must rediscover his best form if Arsenal are to have any hope of securing silverware for a third consecutive season.
The Chilean, who was the Gunners' star man last campaign, has seen the mantle of club talisman switch to German playmaker Mesut Ozil since August.
And with Sanchez now looking devoid of both confidence and form, Wenger must do all he can to coax the best from the ex-Barcelona winger or face their recent spell of success coming to a disappointing end.

The 27-year-old's maiden season in English football saw him immediately become one of the poster boys for the Premier League, with the Chile international shining away from the likes of Lionel Messi and Neymar at the Camp Nou.
He was sold to make way for Luis Suarez yet made a mockery of his £35 million transfer fee by scoring 25 times in 52 appearances.
His finest hour came against Aston Villa in the FA Cup final, where he scored a sumptuous long-range effort to wow a packed Wembley crowd and narrowly lost out to Eden Hazard in the PFA Player of the Year award as a result.
SECOND SEASON BLUES
Despite still hitting double figures amidst an injury-hit campaign, Sanchez is currently enduring the dreaded ‘second season blues’.
Teammate Ozil is now the darling of the Emirates Stadium, with the World Cup winner on course to overtake Thierry Henry’s record of 20 assists in a solitary league campaign, meaning Sanchez has had to share the spotlight.
His performances against Hull City, Barcelona and Manchester United in the past week or so were drab to say the least. It wasn't the first time the winger has flattered to deceive this campaign and the current form of Danny Welbeck will only serve to enhance the pressure to deliver.
Sanchez is an individual whose work-rate can often be as crucial as his creativity, but even he will know that he must improve or face being left out of Wenger’s starting line-up for the biggest games of the season.
The ex-Udinese star was out of the team at the start of the campaign due to fatigue, but with mere months remaining should be hitting his stride rather than struggling to make an impact.
If he fails to rediscover his goalscoring touch, a barren campaign at the Emirates could well be in the offing for the first time since 2013.
