Former Chelsea boss Guus Hiddink says Frank Lampard will know the buck stops with him.

Chelsea went top of the table when they beat Leeds on ­December 5.

Since then, they have lost five of eight games – and ­Lampard is now feeling the heat.

Hiddink told the Mirror: “When it comes to signing players, there is a number of people who are responsible.

“A coach, of course, is part of the process – but it is also about the policy of the club to decide what kind of players you want to attract.

“Many factors have to be considered before making a judgement.

“But the ultimate ­responsibility for results always lies with the coach – and Frank will understand that."
