Millwall have completed the signing of young striker Ajay Matthews from fellow Championship side Middlesbrough.
The ex-Boro apprentice has put pen-to-paper on a long-term contract at the Den.
The England U18s international broke through into Middlesbrough’s first team last season and impressed at youth level, netting eight goals and registering five assists in the Premier League 2.
He has joined Alex Neil’s side for an undisclosed fee.
