I cannot comment much about this match itself as a lot of info is missing (formation, orders, condition of players, and whatever else can be controlled or given by the game to control by the manager), but I would say the following.
It seems that in this game, what is happening is an attempt to simulate what happens in real life football. In football, there happen to be shocking results, upsets or unexpected results like bottom teams beating or getting a draw against top teams. Sometimes such unexpected things put the race for 1st or top 4 open again. But, in real football, bottom teams still train regularly, they still have players in decent physical and mental condition and so on, unlike in Top Eleven. So, this comes to the concern of some active users, where they ask (as some did here on this forum): what does training, morale boosting, managing your team and being on the bench do or what effect do they have if what seemed to be weaker, abandoned teams (no training, no manager present on bench, and so on) can beat active teams? Sometimes it can happen that the abandoned team has by chance a good counter formation and orders set, and hence, this team gets a draw against an active team, or even a win if the abandoned team has enough in terms of quality, but this does not seem to be always the case in Top Eleven. It is clear that there is unfairness, and sometimes this cost active teams important points that are title or top position deciders.
The team currently at first position in my league still did not get an unexpected result or in some way to say 'troll' result so far this season for the league. He is now with 2 draws (against my team) and a loss (against the current 3rd-placed team). Concerning my team, for the league, I got one (a draw) and had difficulties against some teams that I would expect to beat with large scores. So, it could have been more draws and losses if another manager was in my place. No wonder why some active managers have complained a lot on the forum. I would say that some teams are playing at an unexpected level this season, and this has been too frequent in some cases, where an active team suffered more compared to another active team in the same league, hence giving some active teams an unfair advantage in the title race or for top positions.
