Manchester United fans are preparing themselves for Alexis Sanchez’s arrival.

The Chilean said farewell to his Arsenal teammates last night, according to the Mirror, and an announcement appears imminent.

Sanchez has been destined for Manchester for months now but many thought that it would be the blue half where he landed, especially when Man City reignited their interest at the start of the month.

But Pep Guardiola wasn’t prepared to meet Sanchez’s wage demands - he will earn £450,000-per-week at Old Trafford - and City will have to cope with their biggest rivals getting stronger.

From Sanchez’s point of view, it’s easy to understand why he’s eager to leave north London. It’s very hard to get excited about the situation at Arsenal right now.

Shearer reacts to Sanchez joining United

Alan Shearer, however, has questioned his decision to sign for United when he knew that City were interested.

Writing his column for Coral, Shearer believes Sanchez could be missing out on “something special” at the Etihad Stadium.

“If Alexis Sanchez had two years left on his current contract in this current climate he would be valued at around £80m to £100m,” Shearer said.

“If Manchester United get a player of his quality for only £35m, it will be a great deal for them.

“Whether it is the right choice for the player remains to be seen. He could be going to one of the biggest clubs in the world, steeped in history and with a manager that is a serial winner and from that point of view it looks like a very good move for him.

“However, he’s very unlikely to win the Premier League this season at United and it’s impossible to say right now that he will win more trophies than he would at Manchester City.

“There’s something special going on at City at the moment and there’s no guarantee that United can break that up.”

Henrikh Mkhitaryan’s arrival will soften the blow slightly for Arsenal but Alan Shearer doesn’t think it reflects well on the Gunners to see one of their star players running down his contract.

“It won’t send out a good message to the Arsenal fans,” the Premier League’s all-time top goalscorer added.

“If one player lets their contract run down then that can be understood but for three to be in that situation then it is either misplaced loyalty or misguided management.

“Arsenal are lagging behind in the race for the top four now and it looks like the only way they can qualify for the Champions League next season is to go and win the Europa League.”
