Hearts have announced the appointment of former Hibernian and Dundee boss Jim Duffy as their director of football.

And Duffy insisted head coach Graham Rix is picking the team, despite reports club owner Vladimir Romanov has been choosing the line-up.
In an interview with BBC Radio Five Live, he said: "I know it and everyone at the club knows it. The manager is picking the team."
Duffy has previously worked with Rix at Chelsea and Portsmouth.
The former Dundee manager joined the coaching staff at Hearts just two weeks ago but said no-one was in any doubt who was at the Tynecastle helm, despite speculation last week that Romanov picked the team for a game against Dundee United.
"I have been in rooms before when directors have asked me why this player wasn't playing and, when I was young, I thought I was being told what to do," he said.
"There is also a translation problem because Mr Romanov does not really speak any English.
"But Graham is the man in charge and the players know he is the man taking training and picking the team."
Duffy will be in the job initially until the end of the season, although he hoped to stay at the club longer.
"I will try and do the best I can and if I do well enough, hopefully it will be a long-term relationship," he said.
"There are all sorts of things that a manager has to deal with and I will be able to take some of those things off Graham's shoulders.
"If the first-team is winning, then that is the most important thing.
"Sometimes all sorts of things are laid at the manager's door like player recruitment and youth development and that is where I will come in."
Hearts had hoped to appoint a director of football within two weeks after unveiling Rix as head coach in early November.
And Hearts chairman Roman Romanov caused some confusion later that same month when he said a well-known figure was already "working incognito" for the club.
However, Rix, who is also under contract until the end of the season, is delighted to be working with Duffy.
"Jim is certainly a great asset for the club," he told the club website.
"He knows the game inside out and can be fully trusted with all footballing matters here.
"I can now focus on coaching and developing the first team after a couple of testing weeks."
