Inter CEO Giuseppe Marotta said star duo Nicolo Barella and Lautaro Martinez will extend their contracts with the Serie A champions, while he hit out at former striker Romelu Lukaku.

Barella is contracted to Inter until 2024 amid links with Liverpool, Atletico Madrid and Paris Saint-Germain, and the Nerazzurri have been determined to tie the Italy international down to a new long-term deal.

Martinez – long linked with LaLiga giants Barcelona – and his current deal does not expire until 2023.

Marotta addressed the futures of Barella and Martinez ahead of Sunday's Derby d'Italia against rivals Juventus, while highlighting the time needed to re-sign midfielder Marcelo Brozovic, who is reportedly wanted by Manchester United and Barca.

"Barella and Lautaro will extend their contract with a pay rise, we are close," Marotta told Il Corriere della Sera.

"Brozovic's contract is expiring, it will take more time, but I am confident."

Marotta, meanwhile, said there is not much difference between Inter's Edin Dzeko and former star Lukaku – who he claims left San Siro for more money.

After leading Inter to the Scudetto last season, Lukaku re-joined Chelsea in a club-record £97.5million (€115m) deal.

Dzeko was brought in from Roma as a replacement for Lukaku ahead of the 2021-22 campaign.

"Lukaku was sold for €115m and we bought Dzeko for free. On the pitch, there isn't much difference,” Marotta said. "Lukaku left to double his salary, in Italy these figures can't exist.

"Today, we can't make important investments, I wouldn't be allowed to sign Lukaku for €75m. We need reduced and specific investments."

Barella and Arturo Vidal netted in the last home Serie A match against Juventus – the last Inter midfielder to score in consecutive league seasons against the Bianconeri at San Siro was Lothar Matthaus (in 1989-90 and 1990-91).

Among the 13 teams he has faced at least 10 times in Serie A, Juventus are one of the two against which Dzeko has been involved in the fewest goals (alongside Torino) – only three (two goals and one assist).

Inter have scored 78 goals (in 32 games) in 2021 in Serie A. In the big five European leagues, only Bundesliga champions Bayern Munich have netted more (89 in 29 games) this calendar year; Juventus have scored 64 goals in 33 matches.
