The former River Plate forward is expected to start this weekend's Rome derby and is likely to take to the field in a pair of footwear given to him by the Barcelona superstar
The young Argentine, who has one cap earned in a match between locally-based players of Argentina and Paraguay, was called up to the senior national side for their 3-1 victory against Switzerland midweek. Hat-trick hero Messi rewarded the former River Plate player with a pair of his Adidas footwear.
Luis Enrique's men go into the game in sixth place and on the back of last week's 4-1 loss to Atalanta, with Lazio seven points ahead in fourth spot.
Lamela is expected to replaced the suspended Pablo Osvaldo for the game, although Bojan is also a contender to partner Fabio Borini.
Roma will partner Juan with Gabriel Heinze in the centre of defence and will be hoping the Brazilian will act as a good luck charm given his record of five wins in seven Rome derbies.
