Carragher apologizes for misjudging Lisandro Martinez

Jamie Carragher admits that he judged

too early, thinking he could never play the center back role in the Premier League.

"We should never judge managers or players too early, but I’m convinced this can’t work because the size of him playing in a back four,"

he told Sky Sports following the Argentine’s move in the summer

. "Maybe he could go left-back, maybe he could play in a back three, but in a back four, he cannot play there in the Premier League."

Since then Martinez has established himself in

’s strong backline alongside Varane, as well as helping Argentina win the World Cup in Qatar which has prompted Carragher to admit he was wrong about him.

"I think he’s been brilliant. To be that small and play centre-back, you’ve obviously got to be a special player and a good player,"

he told The Overlap

. "I didn’t think someone at that size could cope in the Premier League and he has coped. He’s been brilliant. What I said before about United's spirit, he’s been a big part of that. There was a game I saw a few weeks ago, he was subbed and someone scored a late goal and he was right involved. You saw him in the World Cup, Argentinian, he’s got that fight."
