A teenage thug hit a man over the head with a broken bottle during a drink fuelled New Year's Eve fracas.
Joshua Adamfi, 20, was told he was 'extremely lucky' the victim was not more seriously hurt.
The attack followed a row involving his friend Dale Agg, the victim being in a relationship with the mother of Agg's girlfriend.

The victim had been out at the pub and returned home at about 10.45pm, to get a takeaway and let the dogs out.
Agg's girlfriend had fallen out with a friend, and returned to the victim's home in Rochdale.
Agg, 20, Adamfi and another friend, 19-year-old Brandon Hill, were outside the house when the row broke out on New Year's Eve in 2018.
Neighbours came out of their homes and voices were raised, prosecutor Antony Longworth told Manchester Crown Court.
The victim tried to calm down Agg's girlfriend, and there was a confrontation between him and Adamfi and Hill, who told him that 'Dale was their man'.
Agg 'took exception' to him assisting his girlfriend, the court heard, and hit him.
Wielding a broken bottle, Adamfi then hit the man over the head with it.
He fell to the ground, and he was punched and kicked as he lay on the floor.
The broken bottle caused a cut to the victim's ear, and fragments of glass had to be removed.
"You are extremely lucky that the injury you caused was not more serious than it was," Judge Rachel Smith told Adamfi.
She added: "The three of you continued the assault upon him, he was punched and kicked upon the floor."
The judge said 'serious and life changing' injuries can be caused by the use of broken bottles as weapons.
"Happily the injuries sustained turned out not to be as serious as they could have been," Judge Smith added.
"Each of you was under the influence of alcohol, which clearly played a part in your behaviour and is an aggravating feature."
Adamfi pleaded guilty to unlawful wounding, while Agg and Hill admitted affray.
All three men avoided jail, instead receiving suspended prison sentences.
Adam Roxborough, for Adamfi, said that sending the defendant to jail would 'destroy' the 'significant progress' he has made since.
He works 'long hours' in a warehouse and has since kept out of trouble, the court heard.
"He is a very different young man now," Mr Roxborough said of Adamfi, who was 18 at the time.
"It was an act of stupidity, it was an impulsive act," Agg's barrister Eugene Hickey said.
"He just hadn't thought through the risk that a more mature person might have done, of the violence descending into a spiral of increasing severity."
Mr Hickey said Agg has made progress and has not offended since.
Barry Grennan, for Hill, said the defendant is in work, has not committed any further offences and is more mature now.
Adamfi, of Maldon Street, Rochdale, was sentenced to 11 months in prison, suspended for a year.
Agg, of Curzon Road, Rochdale, received an eight month jail term, suspended for a year.
Hill, of Balderstone Road, Rochdale, was sentenced to 25 weeks in prison, suspended for a year.
All three were ordered to complete 100 hours unpaid work, and 30 rehabilitation activity requirement days.
Adamfi must pay £500 in compensation to the victim.
