West Ham have completed the signing of youngster Daniel Rigge after the midfielder was let go by Manchester City, the London Evening Standard reports.
The 16-year-old has trained with the Hammers previously and has played for the club at youth level earlier this season.
Rigge did go on trial at a number of other clubs but West Ham have now secured his signature on a permanent basis.
The Irons have not had to pay a transfer fee and no compensation is set to be paid to City, due to the deal being done for a free agent.
Rigge is likely to go into the youth teams, likely starting with the U18s but with the potential to move up to the U23s.
Of course, the Irons are also aiming to bring in new additions to the first-team and have targeted a deal to sign Nayef Aguerd from Rennes, while there is also a desire to sign Alphonse Areola permanently.
