Middlesbrough coach Gareth Southgate believes that Manchester United are not invincible despite their current impressive run of results. United are on the verge of booking a place in the UEFA Champions League semi-final after securing a 2-0 victory over Roma at Stadio Olimpico. The Red Devils are also marching towards a second consecutive Premiership title. They will be looking to extend their winning streak to seven matches when they face Boro at Riverside on Sunday. Southgate is aware of United's quality, but remains optimistic Middlesbrough can cause an upset. "We know what they are about and what they're good but at every team has some weakness and we've got to try to exploit that," he told the club's website. "You can't stop them playing because they've got so much individual ability and collective talent. There's no doubt that in the form they're in, they will create chances themselves. "So we've got to think about how we can cause them problems and hurt them," the former England defender added. Midfield Competition Egyptian midfielder Mohamed Shawky will have to fight for his place in the starting line-up against United. Brazilian midfielder Fabio Rochemback returns for Middlesbrough after serving a two-match suspension. George Boateng and Lee Cattermole are also available. Egyptian striker Mido will not take part as he underwent a hernia operation that will sideline him until the end of the season.
