Bayern Munich's close-season transfer targets have already been decided, the club's chief executive Karl-Heinz Rummenigge has announced.
While Schalke have warned Bayern off moving for midfielder Leon Goretzka, Alexis Sanchez has been strongly linked with a switch to the Allianz Arena and Rummenigge said talks with Bayern coach Carlo Ancelotti have produced a list of players to pursue.
"We've already discussed the transfer policy with Carlo and the board and decided on targets," said Rummenigge. "Next season we'll have a team that's more than capable of challenging for titles again.
"We have personnel decisions to make. The transfer activity starts now. Sule has come on really well in the last six months and has also been called up to the Germany squad. He's a player who'll make a positive contribution for us in the future."
Despite cruising to a fifth consecutive Bundesliga title, Bayern were knocked out of the Champions League at the quarter-finals stage and did not reach the DFB-Pokal final after a last-four Klassiker loss against rivals Borussia Dortmund.
But Rummenigge insisted Ancelotti's first year in charge of the club should be judged as a success due to claiming the league title by such a large margin from nearest competitors RB Leipzig.
"I think it's been a good season," the chief executive added. "We won the league by 15 points.
"That's proof that we've worked well over the whole season. Winning the league isn't something you do easily, [It is] excessive to say it hasn't been a good season."
