South is currently in a reliable position. They chased Bangladesh's 106 runs in the first innings and gave a lead of 127 runs for 8 wickets. Considering the field and pitch, this lead is very big for Bangladesh. 5-day matches are rarely seen on the Dhaka pitch, as the pitch deteriorates day by day and becomes challenging for the batters. Spin bowlers have more advantage in this field. Survival on the pitch is the biggest challenge for the batters from Day 3 onwards.
It seems to me that South Africa is in a reliable position because they are in this position. South Africa were under no pressure as their first innings chase of 106 was 127 for 8 wicket. But since Bangladesh is playing at their home play ground, it is a big lead for Bangladesh cricket team. Dhaka pitch used to see less 5 day matches earlier but if you look at the current and past few years you will see that the facility is improving day by day. Although currently they are in a bad position but hopefully it will be over soon. You said Dhaka pitch of Bangladesh cricket gets worse day by day it is not true mate because if you look you will see that there are multiple pitches. In fact, there is no reason to say that it is challenging, but one reason may be that it is difficult to adapt to the soul of another country. The game is not played at home as it is at other places. It is challenging for batter in all countries. It is expected that there will be further improvement in the sports field of Bangladesh.
Since Bangladesh is playing in their home condition, we expected a better performance this time. But seems like nothing changed. They are doing the same thing that they did in India. I don't want to talk about the fielding much. They never been good in fielding except for some special cricketers. It seems like they are doing a government Jobs where is no competition once appointed. They can just relax and work. I think we will have the result soon.
I don't understand why the Bangladesh cricket team is so degraded. Does it seem to depend on the coach or something else? Some doubt the former coach was behind the destruction of a cricket team. Cricket team has been pushed towards the darkness day by day from where it can't come out. The match against India turned out to be a very sad match. So much disaster is coming that it is amazing to think. Again the phone is playing in the field but they aren't seeing any improvement. Let's see the new coach coming and holding his hand if we can see the new light. And our action advisor Asif Mahmud Sojib Bhuiyan will take all the information to take that ticket forward and see what they can do next time.
A lot can be said about fielding. At first they perform very well, later they seem to give up everything and seem to be floating. I think it is the state of mind of Bangladesh to focus only on the game of a player who will do politics and play sports while he is there, how is it possible to do so much at the same time. He can do politics in retirement if he can do it in time. There are many other reasons for the disadvantage of the Bangladesh cricket team.
