Nigerian striker Kelechi Iheanacho could leave Manchester City this summer as Pep Guardiola seeks a major overhaul in his squad after a trophy-less season. The 20-year old international has scored 21 goals for the Citizens since joining the team in 2014, but only featured in 21 games as a starter. Despite Guardiola's confirmation in January that he is including the player in Man. City's future plans, Iheanacho has fallen out of favour since the arrival of Brazilian striker Gabriel Jesus and only played a handful of games since the beginning of the year, mostly as a late substitute. Recent reports in British media claimed that Manchester City could offload him for a tag fee of £20 million. Borussia Dortmund have stepped up their interest to sign the promising forward as he could partner with ace Pierre-Emerick Aubameyang or replace him should the French-born Gabonian player move away from the Westfalenstadion. Southampton and other Premier League clubs have reportedly inquired about loan-moves but it is believed that City will be looking for a permanent move to finance their rebuild.
