Fans of the undefeated University of Central Florida (UCF) football team have challenged this year's national champions.

The UCF fans bought the billboard in Tuscaloosa, Alabama congratulating the Alabama Crimson Tide on their title but also challenging them to play a home and home series with the Knights.

Fans said they originally wanted to put the billboard in Atlanta where the National Championship game was held on Monday but missed the deadline.

The sixth-ranked Knights were left out of the college football playoff but went on to finish the season 13-0 after beating Auburn in the Peach Bowl. Auburn beat both Alabama and Georgia.

While many football fans are chuckling, consider this: the two teams have met once before on the gridiron with UCF beating Alabama 40-38 in Tuscaloosa. That was back in 2000.
