Marcus Rashford is pictured in training ahead of Manchester ...

Marcus Rashford has returned to training for Manchester United amid increasing speculation that he could move to Barcelona before the end of the January transfer window. 

Rashford was pictured training with his team-mates at Carrington on Wednesday ahead of the Red Devils' Europa League match at home to Rangers. 

He was seen smiling during group exercises, with other shots demonstrating his focus on the session. 

Borussia Dortmund are also rumoured to be interested in signing Rashford, who has fallen out of favour under Ruben Amorim.  

Rashford, 27, was not the only player in the squad present at Carrington who has been linked with a move away before the window shuts on February 3. 

Alejandro Garnacho and Antony both trained - with Chelsea and Napoli rumoured to be interested in signing the former while Real Betis could swoop to sign the latter.

Manager Amorim's favoured 3-4-3 setup means he could be open to allowing wide forwards to leave the club in order to replace them with players who may be more suited to a wing-back role. 

One player they seem particularly intent on bringing to Old Trafford is Patrick Dorgu, with the club sending an opening bid of around £23million for the Lecce wing-back  on Tuesday following talks with the Serie A side in Milan.

United director of football negotiations Matt Hargreaves met with agents Frank Trimboli and Leon Angel as well as Lecce president Sticchi Damiani - although Lecce did not come into the transfer window intending to sell. 

'We explained to Manchester that our will at the moment is to try to keep our staff unchanged, retaining all the big ones, especially Dorgu,' said Damiani.

It comes after Rashford’s representatives spoke to Barcelona director Deco on Tuesday - with the Catalans currently in competition with Borussia Dortmund to sign him on loan until the end of the season.

Mail Sport reported earlier this month that Barca have held meetings with Rashford's entourage, with several European clubs tracking the wantaway forward.

Rashford admitted in December that he was 'ready for a new challenge' away from Man United, sparking a scramble for his signature.

Barcelona are understood to have always been Rashford's preference but given his £350,000-per-week wages, they would need to negotiate over the financial burden of a loan deal.

And further talks have now taken place between Rashford's representatives and officials from the Catalan club, which included sporting director Deco.

The talks were held in Lisbon, with Barcelona in Champions League action in the Portuguese city on Tuesday night against Benfica.
