The 25-year-old is yet to appear in the Premier League for the Gunners this season, though his two performances in the Europa League have been impressive.
Wilshere, whose deal expires in the summer of 2018, has been set a December deadline to convince Arsenal he is worthy of a new deal, which he can only justify with regular appearances and an injury-free spell in the team.
If his true desire is to go to East London to have more opportunities in England at the World Cup, he needs to think if the club is a good idea for his career.
Crystal Palace are also being credited with an interest and Wilshere will be aware he needs to be playing regularly as he attempts to force his way back into the England fold ahead of next summer's World Cup in Russian Federation.
Wilshere, who has 34 England caps, has made only three appearances for Arsenal this term and none of those have been in the Premier League. Thus, he has reportedly been discussing a move to the Hammers, but they will have to beat the likes of Crystal Palace to get him in the upcoming window. "I say on the left, but the boss told me before the game that he wanted me to come inside, get in the pockets [of space]". Consistent game time at a strong team in the league might persuade Gareth Southgate to put him on the plane to Russian Federation come the summer - which is Wilshere's main target at this point.
"The boss chose to change the shape past year, it worked well and he's stuck with it. That's probably the best change [I have seen]".
