Alexis Sanchez has been Arsenal's most instrumental player so far this season. The Chilean is currently Arsenal's top goalscorer and looks set to stay there for the remainder of the season.
But will his contribution fire the Gunners past that fourth place position they so often fail to break through?
Of course, it's a bit early to be predicting where Arsenal will finish come the end of the season; however, the performances of new signing Sanchez will give the fans a tremendous amount of belief.
Sanchez justifying price tag
The 25-year-old winger arrived at the Emirates Stadium from Barcelona for a fee of just under £32 million and he has justified that price-tag with some excellent performances for the north London club.
Now, you look at that sum of money Arsenal splashed out on him and think it's a huge fee, but then you turn your attention to Angel di Maria, who cost Manchester United just short of £60 million.

Sanchez best summer signing
If you compare their individual performances together so far this season, Sanchez comes out on top. Arsene Wenger may have found the perfect signing over the summer in Alexis as he looks set to continue his outstanding displays throughout the season and you'd think for years to come.
The tricky little winger has plenty more developing to do as well, whereas he is in his mid-twenties, he didn't get too much game time during his spell at Barcelona, so he has probably learnt more from his short time in London than he did in all his time in La Liga.
Sanchez thriving at Arsenal
Sanchez really seems to be thriving off the fact he is the key man in the team, of course he was never going to be that player at Barcelona with the likes of Lionel Messi and Neymar in the same side. But the move away from the La Liga giants was the right decision for Sanchez as he much more freedom and confidence at a team like Arsenal.
The same has happened to Danny Welbeck. The English striker obviously wasn't going to be the first name on the team sheet at Manchester United with the likes of Robin van Persie and summer signing Radamel Falcao in the squad and Wenger should take a huge amount of credit for their brilliant performances.
He has scouted two players who weren't first team regulars for their club, but clearly have an immense amount of talent and has given them the chance to be key players in his side. The return of Theo Walcott can only be a boost for the Gunners and still have Olivier Giroud to return to fitness.
With all these players performing at the same time, Arsenal can certainly make that all important leap from fourth to the third place finish they always seem to let slip through their fingers.
