Hull midfielder Jake Livermore is expected to join West Brom in the next 24 hours after the two clubs agreed a fee of around £10million.
The 27-year-old is heading for The Hawthorns to iron out personal terms and will undergo a medical ahead of a proposed transfer.
Livermore, who has provisionally agreed personal terms with the Baggies, could be unveiled as a West Brom player as early as this evening.
Livermore has featured in every Premier League game this season but Marco Silva will allow the former Tottenham man to move on in order to fund his own recruitment drive.
Silva is hopeful of signing Norway right-back Omar Elabdellaoui, as well as at least two attackers before the end of the January window.
Livermore initially arriving at the KCOM Stadium on a season-long loan from Tottenham in August 2013 before he signed for £8million on a permanent deal in the summer of 2014.
Albion are also interested in Watford striker Odion Ighalo, although they are yet to make a formal offer.
Ighalo, who has scored just twice in 19 games this season, is on Pulis’ radar but the Baggies are only likely to move for a striker if Saido Berahino leaves this month.
They are in talks with Stoke, who have previously offered £20million, over Berahino, who is out of contract at the end of the campaign.
Ighalo has been linked with a move to China and has struggled to recapture the form which saw him score 17 goals for the Hornets last term.
West Brom have money to spend this month, but are keen to avoid a late transfer scramble ahead of the deadline on January 31.
They made an offer of around £18million for Schneiderlin but he moved to Goodison Park in a deal worth £24million.
There was also interest in Jeff Schlupp, having had two bids rejected in the summer, but the Ghana international moved to Crystal Palace from Leicester for around £12million last week.
Albion had doubts over paying the fee having already had a £12million offer turned down last year.
Pulis has guided West Brom to eighth in the Premier League, but they were beaten 4-0 at Tottenham last weekend.
