Shelbourne manager Joey O'Brien says he expects a sharper Linfield when the teams meet again at Tolka Park in the Uefa Conference League play-offs. The League of Ireland champions edged out the Irish Premiership holders 2-1 over two legs in a Champions League qualifier in July. Shelbourne's recent signing of Sean Moore from West Ham United has strengthened their squad, while Linfield have also made new additions, including Ryan Yates and Sam Taylor. O'Brien feels the main difference from the Blues may be in terms of match sharpness, given that their previous meeting was still in pre-season. The Shelbourne manager has been watching Linfield's recent performances, including their win over Vikingur, and is aware of the threat posed by players like Kieran Offord and Matthew Fitzpatrick. Shelbourne's players will need to be at their best to overcome a sharper Linfield side, with the match scheduled to take place at 19:45 BST. The team's preparation and strategy will be crucial in determining the outcome of the match. O'Brien's experience and tactical acumen will be vital in outwitting Linfield manager David Healy, who has been experimenting with different formations, including playing two out-and-out centre forwards. The match promises to be an exciting and closely contested encounter, with both teams eager to progress in the Uefa Conference League play-offs.
