Cork City have lost midfielder Joe O'Brien-Whitmarsh to Northampton Town. The Republic of Ireland under-21 international has signed a three-year contract at Sixfields. O'Brien-Whitmarsh made his senior debut for Cork City in 2023, before joining Southampton ahead of the 2024 League of Ireland campaign. He played for Saints in the Carabao Cup and FA Cup before departing on loan to Accrington Stanley last season. 'Joe is a highly technical player,' Northampton manager Chris Hogg told the club's website. 'He can play either as a six or a ten in midfield and he will add quality and technical ability to the group of central midfielders we have. 'He has had an excellent grounding and has had experience of the level with a loan spell at Accrington but he now feels it's time to go out and step into senior men's football on a permanent basis. 'He plays centrally, he plays on the front foot, always looking to play forward and he can create. He has a rhythm to his play and he is exciting to watch. Elsewhere, Republic of Ireland defender Tayo Adaramola has joined Cercle Brugge from Crystal Palace. Having enjoyed a loan spell at Sheffield Wednesday last season, Adaramola made his senior Ireland debut against Granada last May. He told Cercle Brugge’s website: 'I’m very happy that I can call Cercle my new home from now on. I had a good feeling right from the very first conversations. I can’t wait to get started and show what I’m capable of.'
