Mason Mount's father has rubbished claims that his son is unhappy after the arrival of Kai Havertz.

The Chelsea midfielder was one of the club's best players last season after a breakthrough campaign.

The England international spent a year on loan to Derby County while Frank Lampard was in charge.

The duo joined back up at Chelsea the following campaign and he missed just one game in the Premier League, while scoring seven.

However, Lampard has been splashing the cash this summer.

Timo Werner, Ben Chilwell, Thiago Silva, Hakim Ziyech and Malang Sarr have joined, but the latest, Havertz, has threatened Mount's position in the first-team.

A report from Bild stated that the 21-year-old was angry at the arrival of the German midfielder from Bayer Leverkusen.

But Mount's father, Tony, rubbished those claims with a series of laughing emojis and a poo emoji.

Starsport understands that Lampard has personally spoken to Mount to outline his plans for him this season.

Chelsea are gunning for silverware this year after missing out on a trophy, though coming very close.

Lampard finished runners-up in the FA Cup after Arsenal beat the Blues 2-1.

The Stamford Bridge outfit also secured Champions League football after finishing fourth in the Premier League.

"Of course he had a big impact on my decision because I loved him as a player and watched him very often," said Havertz after he was confirmed as a Chelsea player.

"And I think I can learn from him as a manager as well.

"I think he's a very humble person, a very great guy, and I can't wait to play with him and learn from him.
