Victor Moses is free to leave Chelsea this summer, albeit on a loan deal, the Daily Star reports.
The former Wigan man is surplus to requirements at Stamford Bridge as Mourinho's ever-expanding wealth of attacking midfielders continue to compete for starting places.
It's now believed that as many as four Premier League clubs are going to go head-to-head for the 22-year-old, who will be allowed to depart Chelsea on a season-long loan.
Currently, West Brom look in pole position to sign the striker, as manager Steve Clarke bids to strengthen his attacking options before the transfer deadline.
Clarke, who maintains a healthy relationship with Blues boss Mourinho, said: "Moses is available to come out and he’s a player we would be interested in.
“But I can’t say I’m confident in landing him or any player at the moment.”
It is believed the Hawthorns outfit have enquired about taking Moses on, but they face stiff competition from Southampton, Everton and Liverpool, who all remain interested in taking Moses on.
