The Red Devils are returning from the United States after taking part in the Premier League Summer Series, having so far made two key summer acquisitions. Matheus Cunha joined from Wolves in a £62.5m deal last month, with Bryan Mbeumo last week following in a move that could cost up to £71m after protracted negotiations with Brentford.

It emerged on Monday that Newcastle, having already seen one offer turned down, returned to Leipzig with a second bid worth an initial €80 million (£69.7 million, $92.6 million), plus a further €10 million (£8.7 million, $11.6 million) in add-ons, as they seek to beat the Red Devils to his signature.
