The flying Jamaican winger made the switch to the Bundesliga from Genk on a deal until 2022 last January, despite the Blues and Manchester United having been credited with an interest.

Bailey, 20, has been in impressive form this term, scoring six goals in 14 Bundesliga appearances and assisting another four.

Antonio Conte is reportedly interested in adding Bailey to a Chelsea squad that has looked stretched this season, with the added games from the UEFA Champions League on top of a Premier League title defence.

However, Leverkusen director Jonas Boldt insisted Bailey is staying put.

"Well now the time starts again when there is insanely much talk," he told Kicker. "We have absolutely no thought of selling him. He has a contract until 2022 - and we are on the driver's seat."
