[Career]Can't stay at my club

This happened to me today. In my case, I was planning on leaving anyway as I won the quadruple for Chelsea. A part of me did want to stay as Chelsea is my team, but was figuring I should venture elsewhere and see what new trophies I could win. I completed all the objectives of multiple clubs, especially Chelsea. When I clicked end season, Chelsea offered me a butt load of money to stay more than any other club was offering, which was enticing me to stay with Chelsea, but I didn't have the option to stay. Why dangle that carrot if I cannot actually stay at the club I deep down really want to stay with.
