United are far from alone in their pursuit of the Hammers star. Liverpool have long been credited with an interest in Bowen as a potential long-term successor to their own attacking stars, while Chelsea are also monitoring the situation as they continue their aggressive recruitment strategy under their current ownership group.

However, United's guaranteed Champions League status and the impending permanent arrival of Carrick as manager could give them the edge in what is shaping up to be one of the summer's most talked-about transfer sagas.
