Manchester United striker Alexis Sanchez feels they should've signed Arturo Vidal.

Alexis' Chile teammate left Bayern Munich for Barcelona earlier this week - though had also been linked with United.

Both Chilean players share the same agent, Fernando Felicevich, and Alexis was disappointed United didn't do more to sign the midfielder.

"To compete at the highest level we need players like him," said the United forward.

"He is a great player and a national team partner, and Arturo Vidal is the example of the type of player we need to win."
