Aston Villa have agreed a deal with Chelsea for left-back Ian Maatsen. Maatsen will sign a six-year deal at Villa Park and Sky Sports News understands talks over personal terms are now underway, with initial discussions described as positive. Maatsen had a £35m release clause which expired earlier this week, allowing Chelsea to negotiate the higher price they agreed with Villa. Borussia Dortmund were keen on signing the left-back on a permanent deal after his successful loan spell at the Bundesliga club last season.
