Cole and Yorke were integral as Manchester United won the treble in 1999.
“They haven’t played a full season together yet,” the United manager said.
“Yorke and Cole scored 52 goals in that season between them, which was exceptional because Yorkie [had] just joined us. It was his first season. Unbelievable. I think Yorkie that season was probably one of the best strikers in Europe. For a first season player he was amazing. He and Andy just hit it off immediately. I would like to hope [Rooney and Hernández can emulate 52 goals] but you never know. It’s a tough league.”
