The coach of Chelsea FC, Frank Lampard, has been sacked after 18months in charge, with the former Borussia Dortmund and Paris Saint Germain (PSG) coach, Thomas Tuchel, due to take over.

It is understood that verbal agreement has been reached between Chelsea and their incoming manager for a couple of days before the news of Lampard's departure became public.

Chelsea confirmed Lampard's exit on Monday morning with owner Roman Abramovich making an unprecedented statement, with Tuchel expected to be appointed in the next 24hours.

Lampard led Chelsea to a 3-1 win over Luton Town in the FA cup on Sunday but the club's premier league form has led to growing concern.

The 42 year old achieved a top-four finish last season, which was deemed impressive having taken over when the club were under a transfer ban.

However, this season, Chelsea spent £220 million ($275 million) on new signings to try and close the gap on Manchester City and Liverpool.
