I think Burnley need to build on their sound defence.
Our outstanding 2019/20 season saw us only concede 39 Premier league goals over the 38 games. This season Liverpool have conceded 41 and won the title. Arsenal with 35 goals conceded are the only team this season to better our 39.
To find a 20+ goal striker in the Premier league is like gold dust. A team needs to play cute and look for chances to score from set pieces. Work hard all week with a quality set piece coach and look for opportunities to create those set pieces in vulnerable areas for the opposition.
Even in the Championship we have to start building from the back and look for a back 6 with the same quality that Hendo, George, Bash, Egan, JOC and Enda gave us.
If we are successful next season then that defence gives us a chance the following year.
Our clean sheet run pre-Xmas should have continued and if we'd replaced Souttar then we could have been now discussing another scenario.
If Wilder is still in charge then building a strong defence is nothing new to him.
On the set piece issue I cannot think of many more wasted opportunities we had than the Robinson long throw. I can only recall one goal resulting from one of these set pieces. Did no-one at the club just question - this is just not working?
