Inter vice-president Javier Zanetti said there has been too much talk about Mauro Icardi amid uncertainty over the star's future in Milan.
Icardi has not played since he was stripped of the captaincy last month, with the disgruntled striker claiming to have been injured but Inter initially said tests could not uncover a specific issue.
"Now we must focus on the field because it is fundamental for the season finale."
Inter are third in Serie A, two points clear of fourth-placed AC Milan following their derby victory prior to the international break.
Zanetti added: "We have the goal of qualifying for the Champions League, 10 games are left and on Sunday we meet a direct rival. The team is preparing for the match as best as possible with the coach."
There has been talk of unrest between Icardi and some of his Inter team-mates as speculation grows over his future.
Inter centre-back Milan Skriniar, however, told Sport.sk : "You should ask Icardi what happened.
"Of course, us players have no problem with him, nor does he with us. It's up to him to put an end to this situation."
Games against Juventus, Roma and Napoli are all still on tap for Inter as the club looks to hold onto their position in the table and earn a Champions League place for next season.
