Romelu Lukaku and Lautaro Martinez were in high spirits on Thursday as Inter stepped up their preparation for this weekend’s Milan derby.

Antonio Conte’s side are one point clear of AC Milan going into the Derby della Madonnina, giving them the chance to open up a gap at the top of the Serie A table on Sunday.

Lukaku, Lautaro, Arturo Vidal and Matias Vecino were all hard at work at Appiano Gentile, as shown by pictures Inter posted to their Twitter profile.
