Much has been made of Manchester United's need for a world-class striker this summer - or their lack of need, perhaps.

While many believe the impending departure of Zlatan Ibrahimovic should see the Red Devils sign a suitable replacement, others insist they already have the necessary quality.

One individual who feels United shouldn't sign a new striker is Michael Owen, who told Goal recently how Antoine Griezmann's potential arrival would hinder Marcus Rashford's development.

"I think Griezmann is a brilliant player, obviously he is brilliant," he said. "What Manchester United must weigh up is, do you spend that £80 million when you have Rashford?

"All of a sudden, for him, you are not sending a great message to pick someone straight ahead of him.

"At the moment it is perfect for Rashford, because you know you have got Zlatan ahead of him but you haven't got Zlatan there forever."

Owen makes a valid point, but if United are to challenge for the Premier League next season, they need a more proven striker than Rashford.

The 19-year-old is hugely talented and has shown over the past year he has a bright future, but now is not the time for Jose Mourinho to make him his No.1 choice.

However, with regards to Griezmann, a move to Manchester this summer might not even happen.

While The Sun report United have agreed a contract with the France international, he has repeatedly insisted he is happy at Atletico Madrid and wants to stay.

Mourinho might ultimately have to look elsewhere for a new striker and, according to French publication L'Equipe, he's already identified his first-choice back-up.

They claim the Portuguese will turn his attentions to Lyon's Alexandre Lacazette in the summer should a move for Griezmann fall through.

While Lacazette isn't as highly rated as Griezmann, he would be a fantastic signing nonetheless.

In 27 Ligue 1 games this season, the French striker has scored 24 goals - second in the top goalscorers charts behind Edinson Cavani.

He's also younger than Griezmann - albeit by a year - and would cost significantly less at around £50-60 million.

What's more is Lacazette is open to leaving Lyon this summer, but according to the 25-year-old himself, he would only join a side in the Champions League.

"[The team I will join] will have to be in the Champions League and play good football," he said recently. "Passing the ball, not just hitting it from box to box. Not kick and rush. That would not work for me."
