But the Jackson to Bayern Munich loan deal broke down after Chelsea asked him to return to the club. That very deal is off and Jackson is back to Stamford bridge. Kolo Muani is on a seasons long loan Tottenham but I don't know the agreement in his contract, if there's an option to buy after the loan spell or not. Kolo hasn't impressed for PSG maybe because he doesn't get game time, in tottenham he will get lots of it, let's see the stuff his made of in that team.
The deal was indeed hampered when Liam Delap suffered an injury and Chelsea decided to call Jackson back to London, but Jackson insisted on staying in Germany, and the loan deal happened just before the transfer window closed. Chelsea has decided not to cancel its agreement with Munich after they successfully recalled Marc Guiu from Sunderland. If only Marc Guiu cannot be brought back to London, then it is possible that Jackson's deal with Munich could be cancelled.
After Chelsea ordered Jackson to come back to England, he refused and that made Bayern to sign a fresh deal with Chelsea with an increase in pay from the initial amount and that Jackson will be permanently signed by Bayern after the loan expired. Marc Guiu from Sunderland will replace Delap. The young spanish player wasn't given much time to play last season as he was always on the bench.
