Crystal Palace have agreed a fee in the region of £35m with Tottenham for Brennan Johnson, talkSPORT understands.The Wales international is also on the radar of Bournemouth and Everton but Palace are seen as front-runners.Johnson could be about to join Marc Guehi at PalaceGettyIt would represent a club-record deal for the Eagles, although Johnson is yet to agree personal terms with the club.talkSPORT revealed earlier in December that Spurs were open to selling him, with the attacker also Bournemouth and Everton’s radar.The Cherries expected the anticipated sale of Antoine Semenyo to Manchester City to free up funds as the winger looks poised to head to the Eithad in a £65m deal.But it appears Palace have now stolen a march on their rivals, agreeing a deal which would see Johnson become the most expensive signing in their history.The estimated £35m fee would surpass the previous club-record £27m to sign Christian Benteke from Liverpool in 2016.Despite Palace shelling out for Johnson, it represents a loss for Spurs, who brought him to north London for £47.5m in 2023.However, this this would still represent the fourth-highest sale in Tottenham’s history — behind Gareth Bale, Harry Kane and Kyle Walker.If the 24-year-old approves the potential switch, he would significantly boost manager Oliver Glasner’s attacking options as they balance domestic and European commitments.Despite finishing last season as Tottenham’s top scorer with 18 goals, Johnson has been out of favour under Thomas Frank this term.He has made just six starts in the Premier League this season, with summer signing Mohammed Kudus being preferred on the right wing.GettyJohnson has largely found himself relegated to the bench this season[/caption]AFPThomas Frank has opted for other options on both flanks[/caption]Johnson’s last start came against away to Newcastle on December 2, having featured off the bench since then.Ironically, his latest substitute appearance came against Palace on Sunday, as he was brought on for the final five minutes of Spurs’ 1-0 win at Selhurst Park.The attacker has made 20 appearances in all competitions this season, appearing on both wings, and has scored four goals.This is in stark contrast to his first two seasons at the club, where he was a regular under former boss Ange Postecoglou.Johnson registered five goals and 11 assists in his debut campaign in north London, helping Spurs to qualify for the Europa League.He then scored the winning goal in the Europa League final in May, as Tottenham lifted their first trophy in 17 years.Shutterstock EditorialJohnson helped deliver major silverware to Tottenham for the first time since 2008[/caption]But the £55m arrival of Kudus, as well as loan signing Randal Kolo Muani, has seen both winger slots occupied this season, prompting Johnson to consider a future elsewhere.
