Manchester United have reportedly agreed terms with Hoffenheim for the transfer of attacking midfielder Roberto Firmino in the summer.

According to Tutto Mercato Web, the Red Devils have reached an agreement with the Bundesliga club and will pay a fee of around £18.3m (€25m, $27m) for the services of the Brazilian international.

Firmino, who joined the German club from Tombense in Brazil in 2011 has been impressive for them in the Bundesliga this season. He has scored eight goals and provided nine assists in all competitions for the German club, and these impressive performances have also caught the eye of the Brazil manager Dunga, who let the youngster debut in November during an international friendly against Turkey.

Apart from United, the player was also being monitored by other clubs from around Europe including Premier League rivals Arsenal and Liverpool.

The Brazil manager has heaped praise on Firmino in recent weeks after the midfielder starred for his country in their game against Chile at the Emirates Stadium. The manager went on to claim that the Hoffenheim star can play for any top club in the world.

"He can play for any club and being on the Brazilian national team that comes a lot easier," Dunga said, as quoted by the Daily Mail.

Meanwhile, United goalkeeper David de Gea is adamant that the Red Devils qualify for the Champions League next season. The Old Trafford club failed to qualify for this season's competition after finishing seventh in the league in their last campaign.

"We have to qualify for the Champions League no matter what. We already missed out last season, and a team like Manchester United cannot do that two years in a row," De Gea said, as quoted on United's official site.

"I'm a composed, calm type, which helps me in my profession. As a keeper, you need to convey a sense of calm to the rest of the team," the Spanish international added.
