The fact that it was a run of games is irrelevant. Like picking up a set of cards and finding that they are all sorted into the right order. They are the same set of cards even when you shuffle them.
A run of draws is worth less than a run of win-lose-win-lose and eventually the desire to keep the unbeaten streak going can lead to a less 'brave' mentality.
What I take from that is our wet blotting paper defence. What on earth is Bednarek doing for their second? He can see that the player is going to shoot yet he doesn't attack the ball and just waits for the shot when you can see him shrink away from it.
He's been doing this all season and it's cost us a fair few goals.
