Ceballos produced a fine display against potential suitors Atletico, his thunderbolt helping Betis to a 1-1 La Liga draw on Sunday.
The 20-year-old youth international has previously been linked with Real Madrid but he wants to honour his contract.
"I have always had a great relationship with Alexis," Ceballos said of Betis' interim coach.
"The thing I'm focused on now is the game against Sporting and concentration on the [UEFA European Under-21 Championship], which we intend to win.
"From that point is where things will start to happen but I have three years on my contract with Betis and my future is here."
Of his performance after scoring his second goal of the season, Ceballos said: "It was my most complete match.
"Because I scored, did well and ran until the very last minute. The team left with a very good taste in their mouth.
"The fans have to be left with a good taste in their mouth and because of that we gave everything. We probably should have won the game. Hopefully, next season we start like that from the first minute."
Betis – 15th in La Liga – face relegated Sporting Gijon in their final game of the season.
