Romelu Lukaku is pictured in a Chelsea tracksuit at Cobham as the Belgian striker tries to force through Juventus swap deal with Dusan Vlahovic

Romelu Lukaku is back at Chelsea’s Cobham training base with his future up in the air ahead of the new season.

The Belgian striker was pictured alongside a Chelsea Under-12 player in an Instagram post wearing a club tracksuit as he keeps up his fitness levels.

Lukaku, 30, isn’t in the plans of new Blues manager Mauricio Pochettino but so far hasn’t been able to secure a move away having spent last season on loan at Inter Milan.

Reports in Italy suggest Chelsea are in talks with Juventus over a player-plus-cash deal for their striker Dusan Vlahovic, with the transfer fee around £35million.

However, Pochettino reportedly isn’t convinced by Vlahovic’s qualities and is unwilling to sanction the deal.

Lukaku is believed to be training individually at Cobham alongside a personal fitness coach and away from the rest of the Chelsea squad.

A return to Inter appears unlikely despite 14 goals in 37 appearances during last season’s loan spell, which featured a run to the Champions League final.

Lukaku was criticised for missing a number of key chances after coming off the bench in the 1-0 defeat to Manchester City.

A permanent move to Inter collapsed with one ultras group labelling Lukaku a ‘mercenary’ who has ‘betrayed’ the club by considering a move to bitter rivals Juventus.

He was linked with a move to Al-Hilal in the Saudi Pro League but wasn’t keen on moving there.

Juventus fans, meanwhile, unfurled a banner opposing his transfer there. The Curva Sud ultras group held up the banner reading ‘Lukaku stay in Milan, we already have a second goalkeeper.’

Chelsea have left the No 9 shirt – which has come to be regarded as cursed after Lukaku, Pierre-Emerick Aubameyang, Gonzalo Higuain, Alvaro Morata and Falcao all wore it – free this season.
