The German club separated with Marco Rose at the end of March and has to make a decision about whom he should bring in as his replacement.
Crystal Palace manager Oliver Glasner is strongly connected to the position, but it is clear that his preference would be to stay in the Premier League.
According to Sky Germany, reporter Philipp Hinze, Fabregas, 37, is a 'concrete' option for the Bundesliga outfit because of his impressive spell in Italy.
Fabregas led Como to promotion to Serie A for the first time in 21 years and currently has in 13th place.
