Manchester United have been warned their acquisition of Edinson Cavani might not go to plan.

The Red Devils - who were desperately scrambling for attacking reinforcements over the last few days - completed the signing of the former PSG hitman on Monday night.

Cavani - who has joined United as a free agent - has penned a one-year deal at Old Trafford, although the option to extend it for a further year is there.

Uruguay international Cavani, 33, arrives at Old Trafford with a proven track record having scored 200 goals in 301 appearances for PSG and 341 throughout his career.

Despite his pedigree, former Tottenham boss Harry Redknapp reckons Ole Gunnar Solskjaer's decision to sign the prolific striker is a major gamble.

"It could come off or it could be a big failure," Redknapp said of United's decision to sign Cavani during an appearance on Sky Sports. "His wages are definitely not cheap.

"Someone told me a couple of weeks back the type of money he was looking for, so it won’t be cheap. It’s a big gamble.”

Unlike Redknapp, Solskjaer is confident Cavani will be a hit at the Theatre of Dreams.

“Edinson is an experienced ultimate professional who always gives everything for his team," the Norwegian said of his new striker. "His goalscoring record for club and country is fantastic and we are delighted to sign a player of his calibre.

“He’ll bring energy, power, leadership and a great mentality to the squad but, most importantly, he’ll bring goals.

"He has had a brilliant career so far, winning trophies at almost every club he has played for, and he still has so much more to give at the highest level."

Cavani is over the moon to have joined United, saying: “Manchester United is one of the greatest clubs in the world, so it is a real honour to be here. I’ve worked really hard during the time off and I feel eager to compete and represent this incredible club.

“I have played in front of some of the most passionate supporters in football during my career and I know that it will be the same in Manchester. I cannot wait to experience the Old Trafford atmosphere, when it is safe for the fans to return.

“I look forward to continuing to write my little story inside the book of football and I know that’s why my focus has to remain the same as always - work, work, work. I have had a conversation with the manager and this has increased my desire to wear this beautiful shirt.”
