I can only presume that they communicate - if a player that Burke recommends doesn't fit into Sami's plans then they don't get pursued. I think Bozza mentioned (or someone else) that Burke had given Oscar a list of great players he was able to get but Oscar turned them all down. I don't think...
That's the incorrect bit. He doesn't solely do that - Sami may have some input into it but that's as far as it goes - the rest is down firstly to DB, then a combo of DB and probably TB as well.
