Jose Mourinho will no doubt wonder what could have been when Chelsea come to Old Trafford on Sunday - in Football FanCast's Fixture in Focus.

Antonio Conte has made significant changes since taking the Stamford Bridge hot seat in the summer, the most obvious being a switch to a 3-4-3 formation and the consequential success of three of his summer signings - Marcos Alonso, David Luiz and N'Golo Kante.

Yet, the majority of the squad hasn't changed since Mourinho lead Chelsea to their fourth Premier League title during 2014/15 - back when some were tipping the west London club to create a dynasty under the Portuguese.

Much of that team was brought to Stamford Bridge by Mourinho himself, so it's likely the now-United boss would be incredibly keen to work with some of the Chelsea cast again at Old Trafford.

With that in mind, we have a curious question for United fans: which Chelsea stars would you like to see Mourinho try and sign this summer? Let us know by voting below...
