Alexis Sanchez is unquestionably one of the most talented players in the Premier League. Since signing for Arsenal in summer 2014, he's gone on to bag 41 goals in 89 appearances across all competitions - including a top flight return of 28 in 61.

Yet amid another underwhelming campaign at the Emirates in which the Gunners have seemingly moved backwards, failing to launch a viable title bid despite the wholesale failings of their closest divisional rivals, it's beginning to feel like the Chile international is wasting his career at the north London club.

That's not necessarily a dig at the Gunners, rather a testament to the 27-year-old's immense quality. Nonetheless, with the summer transfer window looming in, we at FootballFanCast have come up with FIVE reasons Sanchez should look to leave Arsenal at the end of the campaign.

ARSENAL'S INJURY PROBLEMS

Arsenal's injury record is so horrendous one can only assume it's linked with the club's training methods. Alexis Sanchez is a fine physical specimen and a tough cookie who has thus far endured just one lengthy sideline spell since signing for the Gunners at the start of last season, missing nine games after picking up an injury in November.

But long-term injuries have become synonymous with the north London club - whilst the Premier League has a bit of a reputation as well - and sooner or later, the Chile international could pick up one (or multiple) that impacts the rest of his career.

ARSENAL STILL MILES AWAY FROM PL TITLE

A player of Alexis Sanchez's quality should be picking up silverware practically every season and admittedly, his first campaign at Arsenal bore the fruit of the FA Cup. But the Gunners' failure to capitalise on the inadequacy of their divisional rivals this season has proved they're still miles away from the Premier League title - in fact, they've finished 13 points off the top, on average, over the last six seasons.

Many sources have tipped the Emirates outfit to spend big this summer following yet another underwhelming campaign. But until Arsene Wenger's reign comes to an end, it's difficult to envisage the Gunners lifting the domestic title, which brings us nicely onto...

WENGER GOING NOWHERE

There have already been rumours of Sanchez considering a summer departure unless Arsene Wenger steps down and it's not hard to understand why. The north London outfit are clearly stagnating under Le Professeur and the excuse of moving to a new stadium simply no longer washes, especially after Leicester City's shoestring squad beat them to the title this season.

The Gunners haven't lifted the league title since 2004, haven't finished higher than third since 2005 and haven't got past the Round of 16 in the Champions League in six years - including this season. The club is in drastic need of a change in management but Wenger has already insisted he'll be in the dugout for at least next season.

PEAK YEARS

Perhaps Arsenal's lack of silverware and notorious injury problems wouldn't be so much of an issue if Sanchez were still in his younger years, developing as a footballer with plenty of seasons still ahead of him. But the South American is now 27 - peak years for winger-forward of his speedy and athletic description.

In other words, Sanchez is running a real risk of wasting his best years at Arsenal. That's not meant to be an insult to the north London club, but the trophy cabinet is what matters most when you retire and excepting another FA Cup, the Chilean is unlikely to add to his with the Gunners. And there's one trophy that has so far alluded Sanchez, which brings us onto...

The Champions League

Ok, so perhaps Sanchez can accept the dulcet surroundings of London and the love of the Arsenal fan base as consolation for not winning the Premier League title any time soon - he's already lifted domestic honours in Chile, Argentina and Spain after all. But there's one trophy the Chilean failed to get his hands on during his time at Barcelona which, in terms of quality, he more than deserves to lift one day - the Champions League.

And if the chances of lifting a Premier League crown with the Gunners are on the slim side, the chances of winning Europe's top competition are somewhere between slim and none. Arsene Wenger's record at Champions League level is infamously poor - leading Arsenal past the semi-final twice - and during the last six years, they've not even progressed past the first knockout stage.

If Sanchez wants to win the greatest prize in club football, he needs to leave Arsenal.
