The loanee is expecting much transfer activity at Craven Cottage but he feels the club will strengthen even if they lose key players, and is trying to make his move permanent
Sascha Riether is expecting the Fulham squad to look vastly different heading into next season, but is confident manager Martin Jol will keep the club competitive.
Last summer saw Mousa Dembele and Clint Dempsey both leave Craven Cottage for Tottenham while Dimitar Berbatov was the standout arrival as Fulham continue to fight for a mid-table finish.
And with Berbatov a reported target for Russian side Zenit St. Petersburg and veterans Mark Schwarzer and Giorgos Karagounis both out of contract, Reither feels there will be many incomings and outgoings during pre-season.
Sascha Reither is 33/1 with Coral to opening the scoring between Fulham and Reading
"It was not easy for us after losing very good players like Dembele and Dempsey, who scored a lot of goals last season. Our goal was to be in the top 10, hopefully we can reach that and then it is important to build on that for next season.
"There will be a lot of changes in the team this summer. Some new players will join, some players will leave, but we will be prepared for next season."
The 30-year-old is currently on loan at Fulham from German side Koln, but he is attempting to finalise a permanent switch to Craven Cottage after enjoying life in the Premier League.
"You never know what will happen in a new league," he said. "It was not easy coming to another country with a different style of football, but it has gone well for me.
"German football and English football are different, so I had to adapt to a new style of play and new team-mates. Little by little it has got better and I hope that continues.
