Arsenal, Manchester United and Liverpool are all expected to bolster their attacking options before the start of the new Premier League season. It has already been a busy summer transfer window for the Gunners with four new arrivals which should soon become five with an official announcement for Cristhian Mosquera. They are also said to be closing in on a final agreement with Sporting for prolific striker Viktor Gyokeres, despite talk of a Manchester United hijack, in addition to eyeing a move for Eberechi Eze.
