Man United close to sealing deal for Chelsea's Juan Mata

Jose Mourinho has taken a swipe at Arsene Wenger, saying "Wenger complaining is normal, because he always does", after the Arsenal manager voiced his displeasure at Juan Mata's impending transfer to Manchester United.

Wenger suggested that Chelsea's decision to sell the Spanish attacking midfielder to United would give Chelsea an unfair advantage in the title race.

Earlier, Mourinho confirmed that Juan Mata is on the verge of signing for the defending Premier League champions after a significant fee was agreed between the clubs.

Egyptian winger Mohamed Salah is set to join Chelsea as Juan Mata edges nearer to completing his move to Manchester United.

Salah, who currently plays for Swiss champions Basel, is yet to undergo a medical or agree personal terms but the clubs have agreed a fee.

The attacking midfielder, 21, scored against Chelsea in both Champions League matches this season.

"The first step was an agreement with the club. That situation is done, no more discussions, everything is signed and done subject to the medical, that we didn't have yet and subject to the player's desire to join us or not," Jose Mourinho said.

"Now we know he wants to come."

Jose Mourinho has confirmed that Spanish midfielder Juan Mata is on the verge of joining Manchester United.

Mourinho said the offer, believed to be in the region of £37 million, was fantastic when compared to the fee the club paid to sign Mata in 2011.

Mourinho added: "The player deserves respect and to play and because the offer is right, we allowed him to negotiate."

"When the offer came whether he really was happy to go and he said 'yes, I am really happy to go'."

Juan Mata's £37 million move to Manchester United will be finalised sooner rather than later, Jose Mourinho has said.

United are expected to finalise the club-record deal today with Jose Mourinho seemingly happy to let the Spanish international, who has been reduced to a bit-part role under the Portuguese manager, leave.

"Things are going in a good direction. We allowed Juan to travel and have a medical and I think sooner rather than later things will be finalised," Mourinho told a press conference.

"When the offer came I asked him 'are you really happy to go?' and he said 'yes, I'm really happy'."

Juan Mata is growing increasingly frustrated with Chelsea's failure to formalise his move to Manchester United.

The Spanish playmaker has reportedly agreed personal terms on a four-and-a-half year contract ahead of the £37 million move, but the Telegraph reports that the 25-year-old is frustrated with Chelsea's failure to sanction the move as they look for a replacement.

Despite the delay, Manchester United are confident about sealing the deal with Mata expected to travel to the club's training ground for a medical on Friday.

Mata has been voted Chelsea's player of the season for two years in a row after signing for the club for £23.5 million from Valencia in 2011, but has since fallen out of favour under Jose Mourinho.

Spanish midfielder Juan Mata is expected to complete his record move to Manchester United today.

United have reportedly had a bid of £37 million accepted by Chelsea, and Mata is expected to undergo a medical before signing a four-and-a-half year deal.

Mata, 25, has failed to command a regular starting berth under Jose Mourinho and is looking to move on ahead of this year's World Cup.

Speaking after defeat at the hands of Sunderland, David Moyes said:

• It's reported Juan Mata has told Chelsea officials he will not be returning to the club
• His transfer fee would exceed the £30.75 million Sir Alex Ferguson paid for Dimitar Berbatov in 2008

Chelsea's Juan Mata is expected to undergo a medical today before completing his club record transfer to Manchester United. It's reported the deal is "close" to being completed, with Mata expected to be in David Moyes' squad for the visit of Cardiff to Old Trafford on January 28.

David Moyes refused to discuss Mata following Wednesday's Capital One Cup exit at the hands of Sunderland.
