Join us as we look back at Dedryck Boyata's nine-year stay in Manchester following the announcement of his transfer to Celtic.
Beginnings: Dedryck joined City in 2006 and was part of the under-18 team which clinched the FA Youth Cup in 2008.
First-team debut: The youngster made his first team debut against Middlesbrough in the FA Cup in January 2010, playing centre-back and helping his side to a 1–0 win.
League Cup: The youngster was superb in the League Cup semi-final against United - ultimately, City lost, but Dedryck made a big impression and was named the Club's Young Player of the Year for the 09/10 season.
First goal: Boyata heads past Costel Pantilimon for his first senior goal as City overcame FC Timişoara in a Europa League play-off.
Red card: A promising start to 2009/10 continued with a 1-0 win over Chelsea but Dedryck was shown a red card for a foul on Marouane Chamakh in a game he started against Arsenal shortly after.
Red Devils: Boyata made 17 appearances in the 2009/10 season and received his first Belgium cap against Austria in late 2010.
FA Cup glory: Boyata played seven times in the 2010/11 FA Cup as Roberto Mancini's men went all the way to the final where they beat Stoke City.
Loans: Dedryck has spent two periods on loan away from City - he spent the 2011/12 season at Bolton where he made 17 appearances and he also played for FC Twente in 2012/13 where he played eight times.
Return: Since returning from FC Twente, Boyata has played 11 times for City in competitive matches - mostly in the cups.
US Tour: His final trip as a City player was on the post-season tour to USA last week - he leaves City after making 34 appearances, scoring one goal.
Good luck in Glasgow, Dedryck!
