The subs were strange, especially by Mourinho's standards. Surely Lo Celso coming on and going into midfield would have been smarter than Eriksen and then Sissoko coming on.
Think he is giving all the squad a chance to show what they can do - so maybe more strange subs for the next few games. But both Eriksen and Sissoko fluffed theirchances, though I think they will get other chances.
I'm guessing that Lo Celso arrived back from Argentina on either Wednesday or Thursday and Jose might have thought he looked not quite 100% so why not give Eriksen, who should be physically fit, a chance even though Jose said pre match that he had to better understand whether Eriksen wanted to stay and fight or not.
