Emmanuel Frimpong will be out for "six to nine months" after injuring his cruciate knee ligaments in training this week.
The powerful 18-year-old midfielder figured heavily in pre-season and according to Arsène Wenger, was likely to see first-team action during the campaign. Unsurprisingly he described the news as "a massive blow" when he spoke to TV Online on Thursday.
This comes a day after it was announced that Samir Nasri underwent surgery on his own knee problem. Thankfully he will be out for just a matter of weeks.
"Samir's injury is a blow for us and a blow for France as well," said Wenger. "He was continuing his natural progression and had a very good pre-season.
"But we have had another blow with Emmanuel Frimpong. He has done his cruciate in training. That is a massive blow. A cartilage is three to four weeks but a cruciate like that one Frimpong did yesterday is six to nine months.
"I rate him highly and I still have a lot of faith in him but we will miss him for six to nine months."Copyright 2015 The Arsenal Football Club plc. Permission to use quotations from this article is granted subject to appropriate credit being given to www.arsenal.com as the source
