U’s head coach Des Buckingham said: “If you look at Hidde’s CV, he’s played in Serie A and he’s recently played in the Eredivisie. He played at right wing back against Roma and Juventus, so he’s very capable going forward.
“That’s something we saw, but he’s also a very capable defender that we’ve been very fortunate to get from a very good level of football.
“He’s had to be patient, and that’s a credit to him. We spoke about the characters we want to bring into the building, but there’s also a recognition that if a player is playing well in front of you, it’s the same the other way, and if he was playing that way, he wouldn’t want to be taken out unless it was a rest or tactical.
“He’s got Peter Kioso who’s been in very good form and getting better game by game. He recognises that, and that’s important.”
