Well we bought Sanchez and Ozil, so the above line is total rubbish. And when we signed Xhaka, we signed him because we believed he was a quality player. And Mustafi, despite my reservations about him, was regarded as a very good defender too.
And even though Cech is an old man, many still believed him to be one of the top 3 keepers in the league when we signed him.
We are not a selling club and haven’t been for years. The Sanchez situation is simply because he is running down his contract and we as a club cannot hold onto him. The fact we haven’t sold Sanchez when it’s been clear for a while he wants to go is further evidence we aren’t a selling club anymore.
