The Premier League side are clearly desperate to strengthen their options at left-back.
A report in the Express and Star has claimed that West Bromwich Albion have stepped up their efforts to land a new left-back, with Leeds United's Charlie Taylor and Sead Kolasinac of Schalke appearing to be their main targets.
The Express and Star reports that Kolasinac is heading into the final year of his contract with the Bundesliga side and has been rated at around £5m.
With just one signing through the door at the Hawthorns, the Bosnia and Herzegovina international would arguably be an excellent option as while he is predominantly a left-back, he can play in a variety of positions in defence or midfield.
However, it appears that it is Taylor that is at the top of Tony Pulis' list of potential targets in that area of the field. The Express and Star reports that the Baggies had scouts in attendance for the Whites' clash with Queens Park Rangers on Sunday.
Like Kolasinac, the 22-year-old is entering the final year of his contract at his current club, and the Yorkshire Evening Post previously reported that United had turned down a transfer request from the academy graduate.
Although the request was rejected, the move by Taylor would have surely given West Brom hope that they may be able to get a deal done before the window shuts.
While Taylor did not have his best day by any means at Loftus Road - Garry Monk's men fell to a 3-0 defeat - he has shown signs previously which suggest that he is more than capable of playing at the highest level, perhaps leaving Pulis to decide whether he wants Kolasinac's top flight experience or Taylor's potential in his squad.
