Disagree. Our defence has kept us up. Our attackers are DIRE. We have been playing openly in many games (under Sami) and the problem there was the same - scoring goals. I'm Not saying keep the exact same back 4, I'm saying money is best spent in other places FIRST.
Of course the defence needs strengthening. That, however, doesn't make it the top priority. Scoring goals is the most important part of football, without a goal, the best you can hope for is one point. The foundation of every team should be a solid Defence, and then you build from there...
