Ziyech & Aubameyang all smiles returning to Chelsea despite uncertain futures

Hakim Ziyech and Pierre-Emerick Aubameyang were in positive spirits as they returned to Chelsea training despite their uncertain futures at Stamford Bridge.

The pair, along with Romelu Lukaku, were not required to return to Cobham until Tuesday after the squad departed for their pre-season tour in the US on Monday as they are not in boss Mauricio Pochettino's plans.

Both players look likely to leave the club this summer after falling down the pecking order before Pochettino's arrival at the club.

The pair posed for a photo with striker Armando Broja, who is recovering from a cruciate ligament rupture which has kept him out of action since November.

Ziyech shared the image on his Instagram story for his 9.9 million followers with the caption: 'We keep smiling baby.'

Aubameyang, Lukaku and Ziyech were originally due back last week but were given additional time to explore possible moves.

They were then set to return on Monday, only for their comeback date to be pushed back once again.

Ziyech looked set to join Cristiano Ronaldo at Al-Nassr only for the move to collapse at the end of June, as a knee problem was raised during his medical.

It meant that he missed out on a lucrative deal that would have seen him £9m net each year.

The 30-year-old had also looked set to join Paris Saint-Germain on loan back in January, with the Blues failing to complete the paperwork before the deadline on that occasion.

Aubameyang looks closer to leaving the club than the Moroccan, with the Blues locked in talks with Marseille over a potential move.

The 34-year-old joined Chelsea last summer under his former Borussia Dortmund manager Thomas Tuchel but found himself increasingly overlooked under his replacement Graham Potter and also omitted from their Champions League squad for the knockout stages.

That alerted a number of clubs to his situation in Europe, the MLS and Saudi Arabia and it is Marseille who have emerged as leading contenders to sign the 34 year-old.

They finished third in the French league last season securing qualification for the Champions League qualifying round.

Lukaku is another player who looks likely to leave the club, with Juventus moving ahead of Inter Milan - where he spent last season on loan - to become favourites to sign the Belgian striker.
