Pre-season trips are part and parcel of the business we call football. Jet-setting across the globe is a must for any self-respecting club that prides itself on its truly international fanbase.

It means fans from far-flung places can get the chance to see their idols up close, and if we take the cynical, business-like approach - it is also ridiculously lucrative.

Arsenal are currently in Singapore to take part in the International Champions Cup, involving Atletico Madrid - our conquerors in last seasons Europa League Semi-Final - and PSG, as well as other European heavyweights. It is a chance to take the training up a notch, and the squad who are currently in Singapore will most likely make the majority of our squad going into the coming Premier League season.

Those that missed out though, the signs aren’t good.

Carl Jenkinson, Chuba Akpom and Krystian Bielik are among those that have missed the plane for this vital trip. It is the first proper chance for Unai Emery to see his team up against class opposition, to get a real runout. Those that make a good impression here will undoubtedly get a head start for the season in terms of selection.

So for Jenkinson and Bielik, it seems as if their Arsenal career is heading toward the exit door. Bielik impressed in last year's pre-season, but his loan spell to Walsall did not work out as a stepping stone and the Pole is still awaiting his first team debut for the Gunners. Jenkinson is a fan favourite but again, a loan spell last year turned sour for the Englishman - this time at Birmingham City - and Jenkinson will need to show he can return to his previous form he obtained during his loan moves to West Ham a couple of seasons ago.

Emery has made a conscious decision to leave these two at home. Stephane Lichtsteiner and Lucas Torreira have been given extended breaks so their absence can be explained, and while Jeff Reine-Adelaide may also still be at home, his minutes on the pitch for our two earlier friendlies - and his subsequent goals in each - mean that the Frenchman has some hope for his Gunners future.

Bielik and Jenkinson had been training with Emery and his coaching staff in the two weeks prior to the Singapore jaunt, and Emery culling them both from this important trip is a firm signal that these two players will soon be up for sale.

Every member of the squad will view this International Champions Cup as a blank slate, and a great chance to show Emery what they are truly capable of. For Emery, it is a fundamental piece of his preparation as he can continue his stringent training methods and continue to improve fitness - and also gain a gauge on which man is more ready and which needs work.

Roles will be decided for the coming season during our trip - and for Jenkinson and Bielik, they will most likely be arranging terms with other sides pretty soon.
