Wow! I am very confused. I have had a look at the original article, and it is a genuine article in an old-fashioned Spanish newspaper (right-wing enough to have been approved of by Franco, published in Barcelona, and now also published in Catalan, the language of those who want to leave Spain...). Your version is then a very bad translation back into English... The first quote from Wilder could be genuine - preferring British players accustomed to a wet Tuesday evening in Bolton - did he say anything like that after the Bolton match? The jump to Brexit is then totally in the journalist's imagination -there is nothing at all actually said by Wilder. And then a quote from CW that in the Premier League we would need overseas players - again, has he actually said that.. Nothing particularly shocking in that. In the initial ramblings the journo writes of Burnley winning the League in 1960 under Jimmy Hogan; a remarkable achievement for a man who played for them between 1903-05.
If there's a conspiracy here, let's blame Carvalhal and his foreigners in S6...
