Napoli looked like they were dealt a huge blow in the summer following the loss of Kalidou Koulibaly to Chelsea, but they may have already filled the void at centre-back with Kim Min-jae.
In just seven Serie A games and two Champions League fixtures, the South Korean star already looks like a key player for the early season table-toppers following his £16million move from Fenerbahce.
In Naples, Koulibaly was known for his explosive physical strength but it was used in conjunction with strong tactical intelligence.
By contrast, Kim seems to prefer direct aggression - and it's working too.
