The 'substantial' fee was accepted this morning.
In his 119 Chelsea games, Jesper scored 10 goals, including the one that sealed Champions League football against Liverpool on the final day two years back.
20 year old Arjen Robben seems to be the ready made replacement for Gronkjaer.
It is now up to Birmingham to agree personnal terms with Jesper, who is currently out in Portugal with the Danish team.
As soon as any deal is finalised, Chelsea Mad will let you know!
