Armstrong believes former club will recover
Celtic midfielder Stuart Armstrong (left) has backed former club Dundee United to regain their form.
The Tannadice side have not won a Scottish Premiership game since the 23-year-old and winger Gary Mackay-Steven left to join the Hoops on deadline day for a combined fee of around £2million.
In addition to being knocked out of both cup competition by Ronny Deila's side, the revelation that United boss Jackie McNamara had received a bonus for selling the duo has left many Arabs fans unhappy, with the Terrors' misery compounded by the first derby defeat by neighbours Dundee in 10 years in midweek.
Armstrong is confident that the team can get back on track, adding: "I think they have just had a run of bad form which happens to a lot of teams. They have had a few injuries as well which hasn't helped them and four games against us as well.
"They have time to turn it around and I think they will."
Armstrong is pleased with the way he and Mackay-Steven have settled at the Parkhead club, still on course for the treble.
Ahead of the trip to Inverness today, he said: "I think myself and Gary have made a very good start so let's hope that can continue.
"It is nice to hear people say we have fitted in well and done well so far and not looked out of place and that was the main aim coming here.
"To fit in well and then we can focus on improving all the time."
Armstrong is looking forward to taking another step towards the league title - Celtic are seven points ahead of Aberdeen with a game in hand - against third-placed Caley.
