Redknapp was in Holland to watch the Costa Rica international score in Twente's 2-2 draw with Benfica on Tuesday night, but admits a deal for the forward is unlikely as he is more concerned about adding to his midfield, which has been hit by injuries to key players.
"I went and watched the game and watched him play," said Redknapp.
"He is a good player but we are more desperate in other areas.
"I don't think anything is going to happen. He's a good player that I have watched before. I just like going to watch football matches so I thought I'd just go and see the game."
