Manchester City could let Sergio Aguero leave at the end of the season, according to a report. City were handed a two-season Champions League ban last month over Financial Fair Play (FFP) breaches, although they are appealing the ruling. However, that could lead to a big-name exit at the end of the campaign. Manchester City are willing to let Aguero go if they fail to overturn the European ban, according to The Sun. The report says the 31-year-old Argentina forward would be allowed to leave if he indicated he wanted to do so despite being contracted until 2021. Aguero is the Premier League club's all-time leading goalscorer and is enjoying another fine campaign, netting 23 times in 29 games.
