Motherwell boss Graham Alexander says it was wrong to force Covid-hit St Mirren to play against Celtic last night, and says football authorities need to take scenarios like that more seriously.Alexander says the fact the Paisley club didn't want to host a money-spinning Premiership clash shows how serious their situation was, and that the demand on them was harsh.While the former Scotland international understands that scheduling could be an issue, he's coming from a background of playing "50 games a season for 20 years" in England and says it can be done.St Mirren earned a terrific point from a 0-0 draw against Ange Postecoglou's men, but Alexander says that's 'irrelevant', as Jim Goodwin had to recall players from loans at lower league
