#4 Sanchez competes for trophies

Despite all of his footballing qualities, if you had to use one word to describe Sanchez it would most likely be "passion". The Chilean's will to win is second to none and a huge part of his current frustration can be allocated to Arsenal's failure to compete in recent years.
While Arsenal are expected to start their rebuilding phase sooner rather than later, the forward would be moving to a club that has only recently gone through that transition.
After years of not competing for the Premier League title, Manchester United have closed the gap on all teams except runaway leaders Manchester City. Sanchez turned 29 last month and will be eager to spend his best years challenging for every competition he enters.
It remains to be seen whether the Red Devils are truly back on their way to the very top of European football, but it seems as if the short-term success is more likely to happen at Old Trafford than at the Emirates.
