One particular area where the 44-year-old will be looking to improve is his wide attacking department, with more creativity and guile needed at the Hawthorns.
The Baggies were woefully impotent in front of goal last season, ending up with a meagre tally of just 31 Premier League goals scored - the third worst in the entire division.
That wasn't all down to their strikers, though, with a lack of ingenuity and creativity in the final third partly down to their lack of quality in the wide areas too.
The Montenegro winger joined the Hammers from Halmstads in the summer of 2017, for a fee believed to be worth in the region of just £2.4 million, but he has failed to establish himself at the London Stadium.
It could be argued that he was never given ample opportunity to showcase his true worth, though, and he still might have a lot to offer at the very highest level.
Haksabanovic, 19, is incredibly skilful, and possesses a potent delivery that would surely prove to be a great asset for West Brom.
He is at the age now where he needs regular first-team football, and a move to the Hawthorns could be just what he needs to help reinvigorate his stuttering career.
The Montenegrin is a real talent, and if the Baggies could tempt West Ham into selling, it could turn out to be a real coup for the Black Country outfit.
