Rangnick is waiting in the wings to takeover as interim United manager and there was speculation before and during the game - not least from Gary Neville - that the German had influenced current interim boss Michael Carrick's team selection.

Indeed, there have been suggestions that technical director Darren Fletcher was communicating in real-time with Rangnick as images emerged of the Scot wearing an earpiece throughout the game.
But Tuchel claimed he did not see anything new in United that suggested former mentor Rangnick had already imprinted his philosophy at Old Trafford.
Asked directly whether United looked like a Rangnick team, Tuchel told Sky Sports: 'No, not at all.'
