Cristiano Ronaldo watched his Manchester United team-mates take on Wrexham in a training ground friendly - as the wantaway forward's future remains up in the air.

The 37-year-old forward returned to Carrington for a second day on Wednesday but played no part in the behind-closed-doors match. 

Ronaldo returned to the United fold on Tuesday having missed all of the club's pre-season tour of Thailand and Australia having asked to leave Old Trafford.

New signings Lisandro Martinez and Christian Eriksen played against the National League side, with the Dane on the scoresheet. 

Ronaldo had swept back into United's training ground in his £168,000 Bentley on Tuesday morning, sitting alongside his agent Jorge Mendes. 

He joined manager Erik ten Hag, as well as Martinez and Eriksen, for a debrief of the pre-season trip he played no part in having been excused on compassionate grounds.

Ronaldo underwent some medical tests on Tuesday and is likely to be placed on an individual training programme before being reintegrated with the main group. 

The situation hasn't changed, with Ronaldo still wanting to leave United in pursuit of Champions League football this season and the club insisting he is not for sale.

And there was a major blow to Ronaldo's escape act on Tuesday night when Atletico Madrid's president Enrique Cerezo ruled out any move for the Portuguese star.

Mendes had been attempting to engineering a move to Atletico after other European heavyweights including Chelsea, Bayern Munich and Paris Saint-Germain turned down the chance to sign him.

But talking to Spanish radio, Cerezo said: 'I don't know who invented this story about Cristiano Ronaldo to Atletico Madrid. It's not true.

'It's practically impossible for him to come to Atletico Madrid.'

Ronaldo has a year left on his £360,000-a-week contract at United, with the option of another year, and is willing to take a pay cut or a loan move to secure his exit.

United's sixth-place finish in last season's Premier League means they will only be competing in the Europa League in the campaign ahead.

On Tuesday, Ronaldo stopped briefly to greet former boss Sir Alex Ferguson, whose presence at Carrington sparked speculation he had been drafted in to persuade Ronaldo to stay.

But Ferguson was at the training ground for a pre-arranged board meeting and lunch with Richard Arnold, the club's chief executive, and David Gill, the former CEO.

Ronaldo intends to remain professional despite his wish to leave Old Trafford.

He maintained his fitness levels in the gym while away from the pre-season tour but has not been immersed in Ten Hag's methods and tactics.

That has left him playing catch up with the new season looming. United host Brighton and Hove Albion in their opening Premier League fixture on Sunday August 7.

Ironically, United play Atletico in their penultimate pre-season friendly in Oslo on Saturday, before they host Rayo Vallecano at Old Trafford on Sunday.

In his absence, a revitalised Anthony Martial, who spent the second half of last season out on loan at Sevilla, impressed in the centre forward position.
