Broja is a big mistake for me, as he seems to have ignored a lot of what he was doing previously. Basically buying people with a good injury record who are rugged, which has worked well.
We bought a very injury prone player, who was injured at the time of signing him. You can say it's unlucky, but you are massively gambling when you do that, and it's wasted a precious domestic loan spot.
As you say, I'm not really sure Beto is not a fail.at this point too. Hopefully he can change that perception, but we need to see more than 1 really good game IMO.
