3. Toby Alderweireld
Atletico Madrid defender Toby Alderweireld moved to Spain last summer after impressing with Dutch giants Ajax. But, after a frustrating season where he struggled to break into the side ahead of Miranda and Diego Godin, it looks as though the Belgian wants a fresh start. He impressed at the World Cup in an unfamiliar position at right-back and has all the qualities needed to be a top Premiership centre-half. However, any possible transfer wouldn’t be cheap and his desire to play regularly is unlikely to be fulfilled at Arsenal.
