Premier League stats: Alexis Sanchez, Henrikh Mkhitaryan, Jamie Vardy, Kevin Keegan

Who is getting the better player?

Arsenal forward Alexis Sanchez is has joined Manchester United and Henrikh Mkhitaryan is heading the other way in a swap.

Looking at Premier League data since Sanchez arrived at the Gunners in 2014, and Mkhitaryan joined United in 2016, the former scores with more regularity while the latter delivers assists at a quicker rate.

But what else do the stats tell us? And how do Sanchez and Mkhitaryan compare to players already at the two clubs?
