The season in the Eredivisie is over, so we can look forward to the transfer period. What can we expect when the transfer market opens on June 22? FCUpdate will be looking at the transfer summer of every Eredivisie club in the coming time. This time it's the turn of Fortuna Sittard, where Joris Mathijsen has the task of filling the creative positions that have been lost. Fortuna is already facing a crucial summer. In Limburg, a large part of the attacking creativity is threatening to leave the selection. Kaj Sierhuis has played his last game in the yellow-green, Mohamed Ihattaren is waiting for a transfer, and also loan players Lance Duijvestijn, Dimitrios Limnios, and Neraysho Kasanwirjo are returning to their clubs. After the defeat at FC Utrecht, the Fortuna players thanked the traveling fans for the last time this season. For several players, this moment also felt like a farewell. Especially the players who made a difference on the ball this season seem to be leaving Sittard. Sierhuis became the club's top scorer with twelve goals and is now leaving on a free transfer. He would have already personally agreed with FC Utrecht, while also FC Twente and NEC are mentioned. "I keep everything open in principle. It could be, but I know I'm open to an adventure abroad. It doesn't have to be immediate, but I would like to have an adventure abroad in my career", said the striker on Monday evening against ESPN. Also Ihattaren seems to be leaving Limburg, although Fortuna had lit the option in his contract earlier this year. The midfielder was directly involved in sixteen goals (six goals, ten assists) and was of great value in the crucial phase towards survival. Especially in February and March, he took the team by the hand. At the same time, there is still uncertainty about his physical load. All parties seem to be open to a summer transfer. Furthermore, Fortuna also loses Duijvestijn. The loan player from Sparta brought direct extra football and ball security to the team, but leaves because no purchase option was included in the loan agreement. Kasanwirjo played half a season on loan in Sittard and returns in principle to Feyenoord. Also Limnios is being waved goodbye. The Greek had a difficult start, but delivered from February onwards with two goals and eight assists. He also returns to his own club, Panathinaikos. Halilovic also seems to be leaving. His contract was formally terminated by Fortuna, after he hardly played this season. Furthermore, players such as Shawn Adewoye, Daley Sinkgraven, Luka Tunjic, Paul Gladon, Nick Marsman, Hasip Korkmazyürek, Tristan Schenkhuizen, and Niels Martens have an expiring contract, for which a decision must be made by the end of May. Where most of the creativity seems to be leaving the selection, a large part of the defensive axis remains intact. Players such as Justin Hubner, Jasper Dahlhaus, Syb van Ottele, and Philip Brittijn have permanent contracts. Also Iván Márquez and Ivo Pinto are still tied. However, Fortuna had a much less stable defensive season than last year. Only two Eredivisie clubs conceded more goals than the number eleven. Van Ottele had a disappointing year after long-term injury. Márquez started strong, but dropped sharply after the winter break and was even
