£29m Manchester United signing could see Arsenal talisman move on

Ander Herrera has arrived at Manchester United, and Athletic Bilbao are keen on Mikel Arteta as his replacement.

Manchester United have been very busy going into the weekend, with the club spending almost £60 million on two new players to strengthen the squad ahead of an assault on the Premier League next season.

The pair in question are of course Luke Shaw, who arrived from Southampton yesterday, and Ander Herrera, who joined from Athletic Bilbao on Thursday.

The deal involving Herrera was slightly confusing to say the least. All summer Herrera and his agent have insisted he would be staying with the Basque outfit. After securing Champions League football at the new San Mames for 2014-15 it seemed no deal was on the cards - regardless of United interest.

Then it looked like a deal was done. He went round Carrington on Wednesday and underwent a medical. But then United tried to undercut Bilbao on his release clause, so the deal was rejected on Thursday morning. Then Herrera bought out the remaining fee before making his 'dream come true' with a switch to Old Trafford.

The main sticking point is the process of selling a player that Bilbao go through.

The club have high principles, with all their players in some way from the Basque land. With that in mind they always try their best to appear reluctant to sell their players. In the past they refused to sell Fernando Llorente, preferring to wait for his contract to expire. They played hard ball on Javi Martinez - and Bayern Munich ended up spending an obscene amount of money on the player.

So now they have all this money, what do they do with it?

Bilbao will want to replace Herrera in the midfield ahead of the Champions League - which means they have to sign a Basque player.

And it is reportedly Arsenal that are in the crosshairs, and their midfielder Mikel Arteta.

Arsene Wenger is said to be open to the idea of flogging the midfielder in order to bring in a, for want of a better phrase, 'younger model'.

Arteta is from San Sebastian and played for Bilbao rivals Real Sociedad as a youngster and again in 2004.

They have around £30 million to spend on players this summer and are also being linked with Basque stars such as Nacho Monreal and Xabi Alonso - but Arteta might just be the perfect replacement for United bound Herrera.
