RB: Pablo Zabaleta, Manchester City to West Ham, Free
Having been released by Manchester City, West Ham were quick to recruit him on a 2-year deal, making him their first major summer signing.
Zabaleta's arrival will push Sam Byram down the pecking order while forgotten man Alvaro Arbeloa is set to leave the club. He's got loads of Premier League experience having made more than 300 appearances for City, winning two Premier League titles and an FA Cup.
CB: Victor Lindelof, Benfica to Manchester United - £30 million
Victor Lindelof was Manchester United's first signing of the summer, having put pen to paper on a four-year deal, with the option of extending another year. Nicknamed the 'Iceman', Lindelof brings with himself a number of assets that would benefit any team.
The Swede, likened to former United defender Rio Ferdinand, is comfortable with the ball at his feet. Lindelof also boasts an impressive pace and has great mobility.
CB: Michael Keane, Burnley to Everton - £25 million
Having gone a spending spree this summer, Everton have roped in some incredibly talented players. One of which is Michael Keane on a five-year deal.
The 24-year-old's strengths include his calmness in possession and his ability to win aerial duels. His credibility is highlighted by some incredible stats from last season.
He had the fourth highest numbers when it came to clearances, blocks and interceptions.
Ranked number one for successful aerial duels, his calmness is further reiterated as he was ranked third in the number of touches in the box for a defender and registered just three short of most shots in the opposition box by a defender.
LB: Sead Kolasinac, Schalke to Arsenal - Free
Arriving in North London, the 23-year-old reckons his versatility will be key in regard of Arsene Wenger switching to a 3-4-2-1 formation in the latter stages of the league.
Kolasinac played a key pass every 90 minutes last season, outperforming Arsenal defenders in that regard.
A free transfer with bags of potential almost feels like a steal in today's inflated market.
