Kai Havertz is certain he will be allowed to leave Bayer Leverkusen in the summer transfer window.

MEN Sport understand the German international has a 'clear wish' to leave the Bundesliga club at the end of the season with a move to the Premier League the most likely.

Manchester United are believed to be one possible suitor for Havertz this summer but Chelsea currently lead the race to sign him after Bayern Munich pulled out of the running. Real Madrid and Barcelona have also been linked with a move.

Bayern had been made early favourites to sign the 21-year-old but no longer see a move financially viable following their deal to sign Leroy Sane from Manchester City last week.

It is understood Leverkusen are open to selling Havertz at the end of the season if a team can meet their £90million transfer valuation for the player, but Chelsea are believed to be confident in negotiating a lower fee.

Jadon Sancho remains the priority target for United this summer while Chelsea have already completed deals to sign Hakim Ziyech and Timo Werner.

Havertz would have a close core of friends should he make the move to Stamford Bridge, with fellow German internationals Werner and Antonio Rudiger already at the club.

MEN Sport revealed last month Havertz has a 'huge desire' to play in the Champions League next season and views playing time as essential ahead of the rescheduled European Championships next summer, two promises which Frank Lampard's side would be in a good position to fulfil.

Havertz has netted 17 goals and notched nine assists across all competitions this season as Leverkusen finished 5th in the Bundesliga and were finalists in the German Cup. They are still involved in the Europa League and are set to face Rangers in the second-leg of their round of 16 tie next month.
