Finally, the Alexis Sanchez transfer saga looks to be coming to a close.After months of speculation and the whole football world safe in the knowledge that the Chilean superstar could walk from the Emirates for free in the summer, it now seems as though Sanchez is heading to Manchester United.Arsenal will receive Henrikh Mkhitaryan in return, but no cash. It is also understood that the Gunners are finalising a £53 million deal for Dortmund striker Pierre-Emerick Aubameyang, who has 21 goals in 24 games this season.Sanchez is set to depart Arsenal for a mega £400,000-a-week contract, £15m signing-on fee and his four-and-a-half-year deal will make him the best-paid player in the Premier LeagueThe former Barcelona forward was spotted on the Old Trafford turf on Sunday night and all signs point to that deal being announced sometime on Monday.A four-and-a-half-year deal on that money when you're already 29-years-old is pretty crazy, but it's also understandable why Sanchez would take it and, to prize him away, why United would pay it.However, Arsenal boss Arsene Wenger is one man that cannot understand it.Wenger said: “I cannot understand anybody wanting to leave Arsenal. But in 30 years of doing transfers you learn a lot about human beings.“As a professional, it was perhaps his last contract at the top level and an important contract. After that, I accept that because we accepted that we would let him go. After that, we analyse the pros and the cons.“We did what we tried to do and went as far as we could. Even Manchester City moved out of it in the end. That tells you we had no chance to give him a contract.”

It's clear that Wenger thinks Sanchez was motivated by money, but not being able to comprehend why anyone would want to leave Arsenal left Twitter rather bemused to say the least.

When pressed how he is going to fit in his pending new recruits, especially given that the club plays with one out-and-out striker, Wenger did not seem concerned.

“How do I fit them in?” asked Wenger. “I just play the good players. They can always play together. Today all the players we had on the pitch were attacking players. Iwobi, Ozil, Wilshere, Lacazette, Xhaka – they are all offensive players.”
