Create a football jersey inspired by the mascot Blue from the movie Rio

Create a football jersey inspired by the mascot Blue from the movie Rio. The jersey should have a design that incorporates a vibrant blue and black color scheme. Include dynamic patterns that resemble feathers and a modern, sleek look. The jersey should be styled like an American football team uniform, with bold stripes on the sleeves and shoulders. Use the name "Cesitar" on the back, and display the number "2.718" (Euler's number) prominently. Make sure the design includes the mascot, Blue, subtly integrated into the background or sleeves.
