Inter Milan losing the UEFA Champions League trophy to PSG last season won't have any negative impact on their performance next season because when Manchester City defeated Inter Milan in UEFA Champions League final, Inter Milan won the Scudetto in the following season. I believe Inter Milan will compete in the Serie A next season as long as their players are fully fit to play in Serie A.
They are strong and that big defeat in Champions League final is like an accident of Inter Milan. They can compete well in this season if nothing changes at their head coach position while in fact we knew that Inzaghi left the club and joined Al-Hilal. Inter Milan did an appointment of Chivu as their new head coach and I believe it is their biggest weakness in this season.
With an inexperienced head coach like Chivu, Inter Miilan will not have good ability to compete with Napoli for Scudetto. If anyone thinks Inter Milan won't win Scudetto this season, I believe that their main reason is Chivu.
There's no time for a team to dwell on their previous defeat, whether it's in a weekly match, a derby, or the highly anticipated final. They must quickly assess their defeat so they can improve next season.
Many teams lost in the final the previous season but went on to win the title the following season. There's no point in letting a final defeat derail them; it's a sign of a poor mentality. What they need to do is evaluate their performance to improve.
