Celtic have confirmed on their official website that they have completed the signing of Manchester United right back Saidy Janko.
The Swiss teenager played just 45 minutes in the Manchester United first team, and has now left on a permanent basis having spent the second half of last season on loan at Bolton Wanderers.
Janko, 19, now signs for Celtic on a four-year contract, and will be expected to challenge Mikael Lustig and Adam Matthews for the right back spot in Ronny Deila's first team next season.
The right back becomes Celtic's second signing of the summer, following fellow defender Dedryck Boyata from Manchester to Glasgow, having snapped up Boyata from Manchester City.
Celtic fans reacted on Twitter after the completion of the deal, and were largely glad to see Janko arrive, though some had questions over the future of fellow right back Matthews.
Conversely, Manchester United fans were bitterly disappointed to see Janko leave the club, with some even suggesting that he could become a similar case to Paul Pogba - in leaving Old Trafford and becoming a star having had few opportunities with the Red Devils.
Here are some of the reactions from Celtic and Manchester United fans after Janko's transfer this evening...
Unfortunate to lose Janko. Another player not given a shot in the #MUFC team. Sad.— Manchester Is Red (@MUFCisRED) July 1, 2015
Why have we let Saidy Janko leave? He's 18, this better not be another Pogba #MUFC— Adam (@adammcglinchey) July 1, 2015
Saidy Janko has joined Celtic on a 4-year deal, quite surprised as he looked the part for the reserves. Hope it's not a Pogba part 2!— Just Cantona (@JustCantona) July 1, 2015
Saidy Janko could be the next Paul Pogba for #MUFC. Exceptionally talented and not even given an opportunity.— UrbanYogi (@kirangokarn) July 1, 2015
Gutted to see Saidy Janko joining Celtic. Great player with massive potential! Wish him all the best. #MUFC— Wizzard (@7WIZZARD) July 1, 2015
Trying to understand the Janko signing......3 right backs and 1 left back seems strange. Maybe looking to sell Lustig or Mathews?? #celtic— Shaun Dillon (@ShaunDillon3) July 1, 2015
I think we are seeing the benefits of being Jason denayer up last season, saidy janko and boyata both young, hungry players #celtic— Thomas Triano (@thomastriano) July 1, 2015
Can see Matthews leaving now we've brought in Janko— Steven Havelin (@StevenHavelin67) July 1, 2015
The fact that Manchester United fans are not happy at Janko leaving adds to the fact it looks a solid signing.— Mac Eoghain (@MrMacFunn) July 1, 2015
