Jose Mourinho was seen at a friendly between Austria and Russia on Wednesday, as rumours swirl he is after Austrian forward Marko Anautovic.
The West Ham forward has been linked with a big money move to the north of England as Mourinho looks to bring in reinforcements for Manchester United behind Romelu Lukaku.
The two previously had worked together in 2009-10 at Inter Milan, when Arnautovic was on loan from Twente, but the move did not work out.
The forward only appeared in three Serie A contests as a substitute, with Mourinho saying the striker had “the mentality of a child” and claiming he was unmanageable.
