It also makes sense when no other big team wants to sign De Gea after being released by Manchester United at the end of last season. I also thought that the barrier for other teams to bring in De Gea was his fairly large salary so that every team would think twice before actually making a decision. And Bayern Munich will also think twice about bringing De Gea into their squad if De Gea himself still has a fairly high salary. Because every team in Europe is not as rich as the team in Saudi Arabia even though it is a big team.
Confusing with David De Gea position right now after releasing by Manchester United and become free agent still not any teams interested to use his service, seems Bayern Munich can't reach agreement deal due David De Gea ask bigger salary payment. I don't think with Bayern Munich blame with David De Gea level quality as top goals keeper and he has much experience exactly when playing for Manchester United but why difficult reach agreement deal how ever Bayern Munich not spent any cent yet for signing De Gea.
Its classic problem with De Gea want to play for top European level team but he want to earn bigger salary, actually is not problem with highest salary payment if accepted with Saudi Pro League bid offer and playing there.
