I would happily us go defensive if it means we get some points on the board. Ancelotti went defensive when he was struggling with injuries and ground out some results. Yeah, some games we lost, but he set up to try not to concede and build from there.
I don't mind defensive football when it's required. Moyes was primarily defensive for 10 years, ancelotti went defensive when it was required.
Allardyce was always defensive, his issue was he never tried to build on it, we went several games without shooting, I also don't think we needed his style of football at that time.
Ultimately, we need to get points on the board. We have looked shambolic with one defender missing because we have continued trying to play the kick and rush which doesn't work with players like rondon etc. I hope he changes it and hope he buys himself some time with a result.
We have injuries, but brentford are missing 7 first teamers as well apparently. We should be looking to take all 3 points, even in a scrappy, defensive game where we nick it.
