When Manchester United were paired with Paris Saint-Germain in the Champions League last-16 draw in December there seemed likely to be only one winner. United were stuck in a rut under the management of Jose Mourinho, while the French champions topped the toughest section of the group stages. However, much has changed in the two months since. United go into Tuesday’s first leg at Old Trafford on a run of 10 wins and one draw since Ole Gunnar Solskjaer replaced the sacked Mourinho.
