Absolutely this, if we intend to play more attacking football, we need to improve the defence so as not to be over reliant on forward players coming back to defend, they still have defensive duties of course but further up the pitch.
Or Balogun, Bernardo played their regularly at Leipzig, although he was shaky at Watford, there was another game later in the season where he came on and played ok. I'd still like Tavernier tbh, but if it doesn't happen, we do have options.
