Gabriel and Saliba

I came to conclusion that these 2 are our most important players, better to say maybe irreplaceable. I'm not saying Holding did something extremely bad (except dumb pen), it's just it's like our whole team feels more confident when they know they have Saliba and Gabriel behind them. I think these 2 are hardest to replace. For me, losing Partey is less of a blow than losing any of these two. We need Saliba back ASAP. We need to buy center back that is close to being good as these two.
