West Ham have concrete interest in signing Club Brugge winger Noa Lang, according to Ex WHU Employee.
The Hammers are laying the groundwork in terms of scouting targets ahead of the January transfer window. 
And it appears that Lang has emerged as a key target for boss David Moyes.
Ex’s report, which is carried by the West Ham Way, makes it clear that Lang may well be one for the summer, after the expenditure in the summer.
But the 23-year-old has impressed for Brugge and appears to be closing in on a big move away from Belgium.
He has won five caps for the Netherlands and can play across the forward line, although he primarily operates on the left flank.
He has made 93 appearances for Brugge and scored 27 goals, while also laying on 28 assists.
It remains to be seen how much Lang would cost but he is valued at £17m by Transfermarkt.
Read on Wikipedia that he has a Morroccan father and though he plays for Netherlands he considers himself Morroccan. Should get on well with Nayef Aguerd then.
