Chelsea are interested in signing 24-year-old Dutch striker Brian Brobbey as a potential replacement for Liam Delap. Bundesliga club Bayern Munich are also reportedly monitoring Brobbey's development, and FootballTransfers reports that Sunderland will demand a club-record fee of €40m. The player, who has three years remaining on his contract, told ViaPlay last week that he has not been informed of any official interest.
