Gyokeres has been linked with an exit from Sporting in January with a number of Premier League sides linked with the former Brighton and Coventry City. Manchester United are one of those clubs as Amorim is set to take over the underperforming Red Devils later this month.
Speaking about United, O'Hara said: “You look at Ruben Amorim going to Manchester United and think whether they could sign him or not, but they’ve got Rasmus Højlund up front. Højlund needs to improve though or else they may look to bring him in too! He’ll be on everyone’s radar, though. I can’t believe Brighton got rid of him for a million quid – everyone talks about them getting it right all the time with their recruitment, but they got that one wrong! He’s top drawer – fair play to the lad.”
