Jose Mourinho has reportedly made personal contact with the agent of West Ham United attacker Marko Arnautovic.
According to Austrian publication Osterreich, the Manchester United manager has shared text message with Arnautovic's brother and agent, Danijel.
Mourinho worked with Arnautovic briefly at Inter Milan and is interested in bringing him to Old Trafford following his impressive second half of the season with the Hammers.
Last week, Arnautovic admitted he was flattered to be linked with the Premier League giants.
"It's nice to hear, I haven't heard anything from my brother, my agent," he said.
"You can keep asking this question but you'll never hear the answer from me."
