West Brom have signed defender James Chester from Hull City, the two clubs have confirmed.
Former Manchester United youngster Chester has penned a four-year deal at The Hawthorns.
Marseille have signed former Arsenal midfielder Abou Diaby on a free transfer.
It had been expected that Diaby would stay in the Premier League and join West Brom but the Frenchman opted for Marseille.
West Brom have agreed a deal worth up to £8million for Hull defender James Chester.
The 26-year-old is due at the club for a medical on Tuesday afternoon with terms agreed to move to The Hawthorns.
He is expected to tie up the switch within the next 24 hours after leaving Hull's training camp in Austria as Tony Pulis' recruitment drive gathers pace.
The sale of West Brom has hit a hitch after Baggies chairman Jeremy Peace announced talks with a possible buyer had been suspended.
Peace announced earlier this month that an exclusivity arrangement had been set up with one unnamed party but no longer feels they can meet the terms of sale.
"I have today brought to a close the period of exclusivity announced on July 3 and suspended negotiations with the interested party involved over the sale of West Bromwich Albion Holdings Ltd," Peace said in a statement released on the club's official website.
"I entered into an exclusivity arrangement in good faith after agreeing terms for the sale but it is now clear to me that this potential purchaser is unable to fulfil the terms of that agreement at this time."
Boaz Myhill has signed a new two-year contract with West Brom.
The goalkeeper has committed his future to the Baggies until 2017 with the 32-year-old set to start the season as the club's first choice.
He said: "It's great to get my future sorted out. It's never easy being a goalkeeper when you're not in the team but the Premier League is the place you want to be."
West Brom are expected to step up their interest in Liverpool's Rickie Lambert in the next 24 hours.
The Baggies are keen to bring the striker to The Hawthorns and talks are set to take place between all parties, Press Association Sport understands.
A deal could be wrapped up by the end of the week with Albion's transfer activity expected to gather pace now boss Tony Pulis has returned from the United States following their three-game tour.
Pulis is hunting a new striker to help Saido Berahino with question marks over record signing Brown Ideye's future following a disappointing first season in England.
Lambert also struggled to make an impact at Liverpool after a move from Southampton last summer with the 33-year-old scoring just three times in 36 appearances.

The sale of West Brom has moved a step closer after chairman Jeremy Peace confirmed exclusivity has been granted to one interested party.
Discussions have taken place with several groups after Peace made the decision earlier in the year to offer up his 88 per cent share of the Baggies as he "considered strategic options for the future development and legacy of the club".
Speculation has linked a Chinese consortium with the club but there has been no confirmation of the identity of the party to whom exclusivity has been granted.
Norwich have agreed a deal to take Youssouf Mulumbu to Carrow Road on a free transfer.
The 28-year-old will link up with the Canaries on July 1 after his West Bromwich Albion contract expires at the end of June.
Saido Berahino has been ruled out of England's under-21 European Championship campaign hours before the first match against Portugal.
West Brom striker played an instrumental role in England's qualification and had been set to partner Harry Kane in attack.
A statement from the FA read:
"The forward will play no further part in the 2015 UEFA European Under 21 Championship in Czech Republic.
"Benik Afobe of Wolverhampton Wanderers has been called up and will join Gareth Southgate's squad ahead of England's group games against Sweden (21 June) and Italy (24 June)."
