Marcus Rashford can be world class if he improves his poaching: Rio Ferdinand

Manchester United's

Marcus Rashford

can become a "world class" forward if he sharpens his poacher's instincts in front of goal, former defender

Rio Ferdinand

has said.

Rashford scored a late winner in United's 2-1 Champions League group stage victory at Paris St Germain on Tuesday, repeating his heroics from 2019 when his winner sent

Ole Gunnar Solskjaer

's side into the quarter-finals.

Ferdinand said Rashford, 22, can emulate United's all-time top scorer Wayne Rooney who similarly added poaching to his repertoire when he joined the club at a young age.

"I think this kid could definitely be world class if he keeps on improving," Ferdinand said of Rashford on BT Sport. "He needs to add a poacher's element, a couple of scruffy goals a season.

"Wayne Rooney, when he signed for Manchester United, scored outrageous goals. He didn't score the ugly goals but then he got that into his game.

"Marcus scores and creates fantastic goals as well. If he can get that ugly side... this kid can go on to be unbelievable."

Rashford had his best season with United last year when he scored 22 times in all competitions. He is the club's joint top scorer this season with four goals so far.
