This match is very important for both clubs, Fiorentina wants to maintain its position in 4th place because the difference in points with Atalanta, Lazio and Bologna is very narrow so the three clubs are trying to fight for 4th position so they can secure a place to compete in the Champions League, as is Inter Milan who is trying to took over the first position currently occupied by Juventus because Inter Milan wants to win the Serie A title, but Juventus is still Inter Milan's tough rival in the race. So the competition between the two is still quite fierce.
If you look at the head to head records, Inter Milan has a bigger chance of winning, but Fiorentina is not a weak club at the moment because sometimes this club can put pressure on the visiting team, and I think Fiorentina will perform as optimally as possible because this is their home match and of course will perform as best as possible in front of their supporters, but I don't think Inter Milan will let that defeat happen to Inter.
Fiorentina is not a weak team, but in terms of quality and strength the Inter Milan team this season is much stronger than Fiorentina.
Inter Milan has huge motivation, who is currently competing for the top position with Juventus, but so is Fiorentina, who is fighting hard to remain in the top 4 positions in the Serie A standings.
I think this match will be quite balanced and Fiorentina will have a little more advantage because they will be playing at their own home, in front of their own supporters, which will certainly make the confidence of the Fiorentina players much better and that is something the Inter Milan team needs to be aware of.
I think it's a little difficult to predict this match.
