Manchester United are preparing to sign Gremio starlet Douglas Costa as a replacement for Real Madrid-bound Cristiano Ronaldo, according to the Brazilian's agent.
United's network of scouts have been tracking the 18-year-old attacking midfielder for the last two years, but the Premier League champions are now ready to make a firm offer.
"They (Manchester United) have identified four or five possible replacements for Cristiano Ronaldo in the world, and Douglas is one of them," agent Cesar Bottega said.
"We have been contacted by several clubs some time ago, including Manchester (United), but by South American ones as well."
Douglas, who has received rave reviews in his homeland, has four years remaining on his contract with Gremio but reportedly has a £17.8m buyout clause.
The diminutive U20 international is seen as one of the biggest up-and-coming talents in Brazil - alongside Santos winger Neymar and Palmeiras striker Keirrison - and is also a free-kick specialist. Costa generally plays through the centre but can also play on the left.
Since an £80m fee was agreed with Real for Ronaldo, United manager Sir Alex Ferguson has stepped up his hunt for a suitable replacement. Wigan Athletic winger Antonia Valencia is also a target.
