Coventry City manager Steven Pressley has said that he is learning from his decisions and mistakes.
Speaking to the Coventry Telegraph's Andy Turner about his use of substitutes, Pressley said: "I'll be honest with you. I am someone who always analyses my own performance before the team and there are a couple of things I could have done better.
"Ultimately, all managers, on reflection, can change things at different times and hindsight is a great thing.
"But I felt at that time (against Port Vale), we could still score, especially with the players we had on the pitch.
"One of the other things that - and sometimes supporters don't always realise this so it's important to mention - is we're not the biggest of teams. And when you are playing against a team which carries that aerial threat, we have markers in our team and if we take them off, we can have quite an effect on set plays. That effect has a bearing on any substitutions I make.
"There are a number of tactical decisions that on reflection, I should have made but that's what's great about football and a manager - you learn from your decisions and mistakes all the time."
