Very Easy — logic-grid deduction puzzle
Four substitutes came on in the second half, and the rain washed away the sheet that said when each one came on and in which shirt.
In the second half of a group match, the coach started making changes. Wendell, Joaquin, Florian and Magnus came off the bench one at a time, at minute 58, minute 66, minute 74 and minute 81. Nobody else came on in between, so each change followed straight on from the one before. Each of them wore a different shirt number. After the final whistle, the sheet that said who came on when, and in which shirt, was left out in the rain and washed blank. Can you put it back together?
