Chelsea broke the British transfer record on Tuesday to sign Argentine World Cup winner Enzo Fernandez from Benfica for £107m.
In doing so they surpassed the mark set by Man City who paid £100m for Jack Grealish in the summer of 2021.
Graham Potter should be wary however as not many of Britain's most expensive signings have lived up to their price tag.
Virgil van Dijk has been a huge success at Liverpool, though the likes of Romelu Lukaku and Paul Pogba did not work out as hoped after their big-money moves.
