As a player coming onto the pitch for about 15 minutes, it is likely you will only get two or three touches. It is not easy to get into a game that is established and pick up the pace of the game. The first time you touch the ball you need it to be a good one.
Fans think every sub should be some super sub or at least as good or if not better than who they replaced. Subs are a gamble and often successful substitutions are as much luck as good judgement.
It is why sometimes managers are reluctant to make changes. Against WBA FL delayed bringing two players on because we were defending a succession of corners. Leave the players on who are focused and up to match speed.
Once the ball was cleared up to the half way line for a throw in, he brought them on. The delay while the subs come on also helps break up WBA's attacking momentum.
I don't judge subs too harshly. They need a good 20-30 minutes of game time to have a fair chance of really getting into the game. Otherwise it is as much luck as anything. Bassette's job was to come on and just run around with fresh legs to press defenders and be disruptive.
