Swansea have announced the signing of the Argentina defender Federico Fernández from Napoli on a four-year deal for an undisclosed fee.

The 25-year-old, who has 26 caps for Argentina including four appearances at the World Cup in Brazil, is expected to be in Swansea’s squad for their Premier League game against Burnley on Saturday.

Fernández’s arrival will bolster Monk’s center-back options, which currently include captain Ashley Williams, Jordi Amat and Kyle Bartley.

Fernández joined Napoli in 2011 from Estudiantes for £2.5 million, helping them win the Coppa Italia last season during a campaign when they also finished third in Serie A. 

One of the biggest differences between the rich and the poor in the Premier League is the value of kit deals.

Clubs receive annual revenue from both their kit supplier and a sponsor for the front of the shirt.

Manchester United has the EPL's richest deal at a combined annual amount of $108.9 million, followed by Arsenal at $100 million, Chelsea at $80 million, Liverpool at $75 million and Manchester City's $53.4 million deal.

Tottenham comes in sixth at $43.4 million, which then begins a huge drop to QPR at seventh with $19.1 million and Aston Villa at $14.5 million.

Everton ranks ninth at $10.85 million ahead of Newcastle United at $10 million.

Sunderland, Hull City, Swansea City, Crystal Palace, Stoke City, West Ham United, West Bromwich Albion, Burnley, Leicester City and Southampton round out the 11-20 rankings.
