Galatasaray will be facing Antalyaspor, which is 7th in the league right now, whereas Adana will face Goztepe who are 19th right now and Sivas will face Kayseri who are 14th. So, I am guessing that unless something unexpected happens, GS will finish at this spot, or even maybe worse.
Being in top 10 would be fine, but this year was a forgone year anyway and anything between 9th and 13th wouldn't really change too much honestly. They need to get a decent manager, sell all the useless and terrible players they had this year, get as much money as possible (sell them to Qatar if you can, they pay top price usually) and then get a few decent players, because they can't just reroll and try again with same roster, and need even better manager than Torrent.
I don't think that the Galatasaray match is going to have any importance right now because at this moment it doesn't matter if they win or lose because they are obviously not going to finish either in the relegation zone or in the top 4.
So, it is not going to have too much importance. But it is going to be interesting to see which player Galatasaray decides to play in the match. This season is over and I expect better performance from them in the next season.
