I honestly just see it the other way round. I think our inability to score is what puts pressure on the team. I think we feel like we can defend OK, but there's no confidence that we can score. It explains why we can't come from behind, if we concede the first goal heads go down because they don't believe we can get the goals we need to win the game. We've kept 3 clean sheets in 9 league games now which isn't bad. In the 5 games we've lost we've scored a total of 2 goals, and in 2, arguably 3 of them, we've conceded the second goal as a direct result of desperately trying to get a goal ourselves. We had plenty of chances to score against Bournemouth and Villa but didn't take them, if we'd managed to take one we could have managed the game better and not conceded again.
We still need another centre half, but for me either a new striker or a big improvement from one of the ones we have is absolutely vital if we're to progress past where we've been for the past few years. The new centre half would be alongside Mina, who is starting to really look the part.
