3 out of 4 of them have been mediocre in a top level league already. Spending probably at least 60m on these would be the answer to get promoted, but would most likely struggle again in the top flight.
Still took Mathew Ryan to Lens last season, he is out of contract now and left Lens. Would be a good cheap GK for this league if we need a goalkeeper with bags of top flight experience.
Its 'only' 12m ish for that disney deal. Its why they are going for old freebie players - owners don't want to put their own cash in. 12m makes a difference in the lower leagues, not so much for them now.
