Johan Mjallby has said that Celtic’s recent form has been “wonderful” and is the result of players working hard as a unit.

The Parkhead assistant manager saw his side rack up their 16th consecutive domestic win with a 4-0 victory over hearts at Tynecastle on Wednesday night.

The result opened up a four point lead in the title race and Mjallby said that the key to continuing a successful run was application and belief.

"We started this run after being very inconsistent,” he said. “We were pressing that you need to work hard as a team.

"We know we have so many good players and they are skilful but to get success you need to work and be a team.

"For the last three months it's been wonderful to watch them. We can win in style and we can win with true grit.

"I think that's the most important change - even when things aren't working, we never panic.

"We believe in ourselves and we try to grind them down and get three points."

Mjallby reflected on the win at Hearts, which manager Neil Lennon has called the best performance in his time at the club, and said that the quality of performance was a result of confidence.

"It was just pure masterclass," he enthused. "It was a brilliant performance from the boys.

"You always worry that you drop your standards in the second half.

"We just wanted to win the second half and they all went out and played so well - you could see the confidence."
