Manchester United have announced Alexis Sanchez has broken the club's records for shirt sales and social media interactions since joining from Arsenal in January.

He said: "Alexis Sanchez has set a new January signing record in terms of shirt sales - three times that previous record.

"This trade (Sanchez's move to United) generated some interesting social media stats.

"It was the biggest United post on Instagram with two million likes and comments, the most shared United Facebook post ever, the most retweeted United post ever and #Alexis7 was the number one trending topic on Twitter worldwide.

"To put all that into context, the announcement posts generated 75 per cent more interaction than the sale of the world's most expensive player last summer when Neymar moved from Barcelona to PSG."
