Nigeria’s Alex Iwobi has agreed a bumper new long-term Arsenal deal keeping him at the club until 2021. The Gunners have handed the exciting teenage forward a five-year contract worth in the region of £30,000 a week. Iwobi only signed his previous deal, understood to be worth up to £10,000-a-week, last October. That agreement was due to run until 2019. But he has made big strides since then and boss Arsene Wenger was keen to reward the 19 year-old academy product with improved terms. Iwobi has become a regular in the Arsenal first team since the turn of the year. He has started four of the last five games and followed up his first goal against Everton before the international break with another strike against Watford on Saturday.
