Celtic have signed 21-year-old defender Tyler Blackett on a season-long loan deal from Manchester United.
The 21-year-old was introduced to the crowd at half-time in Saturday's 3-1 win over St Johnstone, which took Ronny Deila's side to the top of the Ladbrokes Premiership.
Blackett, who has had previous loan spells at Blackpool and Birmingham City and has been capped by England at U21 level, will wear the No 2 jersey.
