The football expert Paul Merson believes that the Armenian international could be an Arsenal sensation after he lost his way at Manchester United.
This transfer window Mkhitaryan is set to join the Gunners in a swap deal where Sanchez will join the Red Devils.
In 2016 Henrikh Mkhitaryan joined the Red Devils from Dortmund, but under the special on he was not able to get the desired playing time what he was looking for in this season.
In an interview at Sky Sports Merson stated: "I am a big fan of Mkhitaryan.
"I watched him at Dortmund, where he was voted player of the season and scored plenty of goals. He has lost his way at Manchester United but if Arsenal get him, with the way they play and the way Arsene Wenger is going forward with attacking players, I think he will be a sensation.
"He is a great signing for Arsenal if they get him.
"Sanchez is top drawer, but to get that kind of quality in January is very rare. Mkhitaryan is one of the best in the Premier League. Any offensive player going to Arsenal under Arsene Wenger is a good move."
This season along with Mkhitaryan, Arsenal is on the verge of signing the Dortmund star Aubameyang.
