United sign four, Partey joins Gunners and Bayern make double move

Manchester United made four signings on transfer deadline day, including Uruguay striker Edinson Cavani while European champions Bayern Munich strengthened with two new arrivals.

But the biggest single move of the final day of deal-making was midfielder Thomas Partey making a 45 million pound switch from Atletico Madrid to Arsenal.

United signed Cavani on a free transfer, Brazilian left back Alex Telles from Porto, Uruguayan 18-year-old winger Facundo Pellistri and reached an agreement to sign Atalanta's teenage winger Amad Diallo.

European champions Bayern signed right back Bouna Sarr from Olympique de Marseille and brought back Brazilian winger Douglas Costa on loan from Juventus.

Arsenal met the 45 million pound ($58.40 million) release clause for the 27-year-old Ghana international Partey who should add some steel to their midfield. Arsenal's Uruguay midfielder Lucas Torreira moved in the opposite direction on loan.

United's 6-1 thrashing at home by Tottenham Hotspur on Sunday has increased the pressure on chief executive Ed Woodward to give manager Ole Gunnar Solskjaer some new options. Attacking full back Telles and experienced former PSG forward Cavani now join Netherlands midfielder Donny van de Beek, who moved to United from Ajax last month.

Cavani was a free agent after leaving Paris St Germain and said he was looking forward to the challenge at Old Trafford.

"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," he said.

Solskjaer said he was hoping Cavani could add to the team's fire power.

"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," said the Norwegian.

Pellistri joined United from Club Atletico Penarol on a five-year contract, with an option to extend for a further year.

The speedy teenager has already featured 37 times for the Uruguayan Primera Division club's first team.

Highly-rated Ivorian Diallo, 18, whose signing could cost United up to 37 million pounds including add-ons, is not expected to join until January due to work-permit issues.

Everton, who have had a 100% start to the season and lead the Premier League, added another defender to their squad with centre-back Ben Godfrey joining from Norwich City.

Carlo Ancelotti's team also brought in Sweden goalkeeper Robin Olsen on a season-long loan from AS Roma.

BAYERN STRENGTHEN

The right back position had long been a focus for Bayern, who won the Bundesliga and Champions League last season and the 28-year-old Sarr joins from Marseille on a four year contract.

"Bouna Sarr is a dynamic right back who fits in very well with the way we approach our game. He'll help us in an important position," said Bayern's board member for sport Hasan Salihamidzic.

Douglas Costa left Bayern for Juventus three years ago and will add to the club's already impressive options in the wide areas.

Paris Saint Germain signed 27-year-old Brazilian midfielder Rafinha from Barcelona on a three-year deal.

In Italy, the biggest move of the day was Juventus signing Fiorentina winger Federico Chiesa in a 50 million euro deal.

The 22-year-old was raised at Fiorentina and is the son of former player Enrico Chiesa who was in the team which won Fiorentina's last major trophy, the Coppa Italia in 2001.

Juve's major signing for this season was Brazilian midfielder Arthur from Barcelona. They have also signed Alvaro Morata from Atletico Madrid and U.S. midfielder Weston McKennie from Schalke 04.

Napoli signed striker Tiemoue Bakayoko from Chelsea on loan, re-uniting with manager Gennaro Gattuso, who was at AC Milan when the Frenchman spent a spell on loan at the San Siro.
