Manchester United have tabled an offer for Uruguayan defender Guillermo Valera.

The 20-year-old, who plays for Penarol, has recently been on trial at Old Trafford and the Red Devils have now lodged a bid around £1.2m for the right-back. The offer has been rejected but the Montevideo-based club is ready to negotiate a better deal.

"It's an important offer. It's complicated - it's not easy," the Express quoted Penarol vice-president Edgard Welker.

Valera is preparing to represent Uruguay at the summer's U20 FIFA World Cup in Turkey. The youngster stated he enjoyed his stint with the Premier League champions and also thanked United striker Chicharito for his help during the trial.

"It was a surprise to get the chance to test with Manchester United. I'm glad and happy, and grateful to Penarol who allowed me to travel. I was treated so well and Chicharito helped me a lot. The work outs were short but very demanding," the defender said.

David Moyes is understood to be keen on signing a right-back this summer. United have only one specialist in that slot: 22-year-old Brazilian Rafael da Silva.

David de Gea Reveals University Plans

Meanwhile, United goalkeeper David de Gea claims he would have gone to university to obtain a degree in history or sports, had he not embarked on a football career. The Spaniard moved from Atletico Madrid to United in 2011 as a 20-year-old in a £19m deal, which remains the British record transfer fee for a goalkeeper.

"I guess if football wasn't an option, I would have concentrated a bit harder at school and put my mind to my studies. I would probably have gone to university and tried to attain a degree related to sport. I also enjoyed history at school, learning about important dates and events," de Gea pointed out.

The 22-year-old kept 11 clean sheets from 28 Premier League matches last season to help United clinch a record-extending 20th top division title.
