Surgery hailed a success for Stu

CELTIC midfielder Stuart Armstrong has declared his trip to Germany for surgery a success.

The 25-year-old midfielder is set for a period out of action after reportedly undergoing a hernia operation after stopping off on the way back from a winter break with the Scottish champions in Dubai.

Armstrong wrote on his Instagram account “successful trip” as he happily posed for a picture w i t h C e l t i c ’s head physiotherapist Tim Williamson at Munich airport yesterday afternoon.

The former Dundee United player, who joined the Hoops i n 2015, will likely miss the William Hill Scottish Cup tie against Brechin City at Parkhead on Saturday.

Meanwhile, Celtic defender Erik Sviatchenko has j oined f ormer club Midtjylland on loan for the rest of the season.

The 26-year-old had not featured for Celtic since the Champions League qualifiers despite recovering from a knee injury several months ago.

The centre-back had been told to find a new club and he has gone back to Danish league leaders Midtjylland two years after making the opposite journey to Celtic, where he has made 63 appearances.

The five-time capped Denmark defender fell further down the pecking order following the arrival of German Marvin Compper.

The Dane was keen to secure regular game time in a bid to rekindle his hopes of making his country’s World Cup squad.

He said: “I knew I had to find a new club and I had other options.

“When I had to choose, I did not doubt I wanted to go back to Midtjylland — the club of my heart, the club of my youth.”
