Mepham, originally on Chelsea’s books, has been at Brentford since the age of 14 and graduated into the first team two years ago. His displays last season earned him senior international recognition with Wales and alerted Bournemouth to his potential. Southampton have also tracked his progress and could rival their south-coast rivals’ interest but, despite the player having been injured just before Christmas, Bournemouth are looking long-term and have moved first.Bournemouth have no interest in parting with their England striker Callum Wilson this month despite reported interest from West Ham and Chelsea.Celta Vigo are close to securing the Netherlands utility player Jaïro Riedewald on loan from Crystal Palace for the rest of the season. The 22-year-old moved to south London from Ajax in 2017 for around £8m but has found first-team opportunities limited. Share on WhatsApp Bournemouth Oumar Niasse has agreed to join Cardiff City on loan from Everton until the end of the season, when the Welsh club would have the option to make the deal permanent.If they chose to take it, the total cost of the package would be £10m, including the loan fee.

Share on Facebook news Share on Twitter Share on Messenger Share on Pinterest Reuse this content Share on LinkedIn Share via Email Niasse has been out of the picture under Marco Silva at Everton this season, playing only 58 minutes in the Premier League across five substitute appearances, and he is eager for more regular opportunity. The Senegalese believes he will get it at Cardiff, where the need for greater firepower is clear. Neil Warnock’s team, who sit 17th in the Premier League – one point above third-bottom Newcastle – have scored 19 times in 22 matches in the competitionWarnock has wanted a new striker since the beginning of January and he has appeared close, at times, to signing Emiliano Sala from Nantes. The Argentinian is the third top scorer in Ligue 1 with 12 goals. It is unclear at present how Cardiff’s move for Niasse will impact on the pursuit of Sala.Niasse has experienced an up-and-down career in England since his £13.5m move from Lokomotiv Moscow in February 2016. He struggled under Roberto Martinez at Goodison Park and was then frozen out by Ronald Koeman before he enjoyed a positive loan spell under Silva at Hull.Remarkably he returned under Koeman at the start of last season, most memorably coming on as a substitute to score twice in a 2-1 home win over Bournemouth. He continued to feature under David Unsworth and Sam Allardyce and he finished the season as Everton’s second top scorer with nine goals. Despite his relationship with Silva from Hull, it has not worked out for him this time.Bournemouth hope to continue their mid-season revamp after opening talks with Brentford over a potential deal for the highly rated Wales international central defender Chris Mepham, who is likely to cost in excess of £15m.The club’s interest in the 21-year-old is longstanding, with inquiries having been lodged with the Championship club in each of the last two transfer windows and a £10m offer rejected over the summer. Yet, with Chelsea contemplating exercising a buy-back clause on Nathan Aké in the summer, Bournemouth are keen to add to their defensive options and are hoping to push through a deal this month.
