While it may be just a slight anomaly, the Portuguese will also have in the back of his mind that he remains without a win over Koeman in the Premier League since the former Barcelona captain took over the reins at Southampton in 2014.
Manchester United manager, Jose Mourinho claims Wayne Rooney is true Red Devils legend and will get a good reception at Old Trafford on Sunday.

Lukaku scored 87 goals in 166 appearances across all competitions for Everton. I think that Romelu has a better team than Zlatan had. But recent history has been kind to United against The Toffees, as they have lost just one of the past six Premier League matches against the Merseyside club.

Long-term issues plague Yannick Bolasie, Ramiro Funes Mori and Seamus Coleman. Pogba will also miss next week's game against Burton Albion in the Carabao Cup, a fixture which in all likelihood he would have sat out anyway, and faces a race to be fit for United's clash against Liverpool at Anfield on 14 October.
