Chelsea Reignite Jackson Transfer Talks with Bayern, Consider Guiu Recall Amid Striker Shortage

Chelsea are back in talks with Bayern Munich over the transfer of Nicolas Jackson after the player pushed to revive the move, sources have told ESPN.

The west London club had last weekend agreed a deal to loan Jackson to Bayern for an initial €15 million ($17.5m) fee with an option to make the move permanent for a further €65m ($76m).

However, Chelsea called the move off after Liam Delap suffered a hamstring injury against Fulham which could sideline him for two months -- or perhaps even longer.

But Jackson was already in Munich ahead of a proposed medical and sources say he is still desperate to join Bayern.

Chelsea have moved to recall Marc Guiu from Sunderland to provide cover for João Pedro -- the club's only fit recognised senior centre-forward -- and sources say they are open to discussing Jackson's permanent departure with Bayern over the coming hours.

Guiu only joined Sunderland on Aug. 6 but is set to return amid a striker shortage at Chelsea.

Academy graduate Tyrique George played up front against Fulham following Delap's injury with Pedro operating as a No. 10 behind him. George could yet leave the club before tonight's deadline amid interest from Roma.

Chelsea have therefore been looking at alternatives. Sources say they enquired about Conrad Harder at Sporting Lisbon but he chose to join RB Leipzig and is flying to Germany to complete a move. Wolves' Jørgen Strand Larsen is another player of interest.

Netherlands striker Brian Brobbey, meanwhile, is swapping Ajax for Sunderland, in a deal worth up to €25 million ($29.3m), sources have confirmed to ESPN.

Sunderland are having an active transfer deadline day with Brobbey set to join his Dutch teammate Lutsharel Geertruida in signing for the Premier League side. While Geertruida is joining on loan from Leipzig, Brobbey is set to sign on a permanent deal for a fee in the region of €20m, with €5m in addons.

Brobbey is yet to appear for Ajax in the Eredivisie this season and the 23-year-old will head to the Premier League to bolster Sunderland's attacking options.
