Can Robinson work Hampden magic against McInnes' Rangers?

While Robinson's position has been relentlessly scrutinised, this semi-final is no less important for Rangers boss McInnes.

One league title, one Scottish Cup, and one League Cup in 14 years is an embarrassing trophy return for Rangers given the money the club have spent.

McInnes is the latest manager charged with changing that after two trophyless campaigns at Ibrox, last season being the first under American ownership who have invested heavily.

Despite consistently showing his managerial abilities, in particular when almost winning a sensational title with Hearts last term, McInnes only has one major trophy to show for it.

That was the League Cup he won in 2014 when in charge of Aberdeen, who he led to Hampden regularly, only to come up against Treble-winning Celtic sides at every turn.
