Nicolas Jacksons final goal for Chelsea was in the Conference League final against Real Betis
Chelsea have agreed an improved package for striker Nicolas Jackson to join Bayern Munich.
After an on-off transfer saga, the 24-year-old is set to complete an initial loan move for £14.3m (16.5m euros), which crucially includes a mandatory obligation to buy for £56.2m (65m euros) through a minimum number of appearances.
Its a deal on slightly improved terms as the one initially agreed and now worth in excess of £70m.
Personal terms are already in place for a future five-year permanent contract for Jackson, whose deal with Bayern was in doubt after Chelsea instructed him to return when Liam Delap was injured in Saturdays Premier League win over Fulham.
The Senegal forward joined Chelsea from £32m from Villarreal in 2023 and scored 30 goals in 81 matches.
To boost their own attacking options, Chelsea have signed Argentine Facundo Buonanotte, 20, on a season-long loan deal from Brighton for a £2m fee.
Jackson had been an automatic starter until his red card at St Jamess Park in April - his second dismissal of the season - which left the club without a striker as they were competing for a place in the Champions League.
Jackson was then sent off within four minutes of coming on as a second-half substitute in the 3-1 group-stage defeat by Flamengo at the Club World Cup, Fifas expanded competition which Chelsea ultimately won. Strikers Liam Delap and Joao Pedro arrived to replace him during the tournament.
Multiple sources with knowledge of the situation said Jackson ultimately lost the trust of manager Enzo Maresca and some of the hierarchy at Stamford Bridge, prompting Jackson to seek a move.
It was a shift in mood as Maresca said earlier in April that the frontman was his "perfect number nine" and wanted "a copy of Nico" rather than to replace him.
Jackson could face Chelsea on September 17 (20:00 BST) in Munich as Uefa rules allow loanees to face their parent clubs in the Champions League.
Chelseas transfer plans were turned upside down after Delaps injury, which could sideline him for "six to eight weeks".
The Blues had earlier that day made an offer to sign Barcelona forward Fermin Lopez, but were then forced to switch focus to sorting out the striker situation.
They initially opted to withdraw permission for Jackson to conduct a medical with Bayern, although he still wanted to join the Munich side.
Chelsea were then keen to negotiate a permanent sale to fund a move for Sporting striker Conrad Harder. However, the 20-year-old was already in advanced negotiations with RB Leipzig and chose them, with an offer of a more important squad role on the table.
The Blues have now opted to recall Spain striker Marc Guiu, 19, from his season-long loan at Sunderland.
Guiu scored once in his only start with a further two substitute appearances at the Stadium of Light, but fills the Delap void and is likely to deputise in-form striker Joao Pedro.
Chelsea hijacked Leeds Uniteds move for Buonanotte and will pay about £2m to sign the twice-capped Argentina international on a temporary basis.
The forward spent last season on loan at Leicester City and managed six goals and three assists in 35 appearances as the Foxes were relegated from the Premier League.
Chelsea have several staff members who know Buonanotte well from their time at Brighton, including co-sporting director Paul Winstanley and director of global recruitment Sam Jewell.
Marescas side have already added another Argentina forward, Alejandro Garnacho, from Manchester United for £40m.
Meanwhile, fellow Brighton forward Julio Enciso, 21, is also expected to join Chelseas partner club Strasbourg for £13.8m, with a view that he will play for the Blues after a year in France.
