England forward Marcus Rashford has suffered a “slight knock” in the final training session before heading to the World Cup in Russia, manager Gareth Southgate said. The 20-year old, who scored 13 goals for Manchester United in all competitions last season, will be hopeful of a starting spot in Southgate’s team after impressing in the warm-up games, including a long-range goal against Costa Rica. “Marcus took a slight knock but nothing too serious so we will have a look at that ahead of tomorrow’s session which is open for everyone to see,” Southgate told British media. “We have another week of preparation and a lot of competition for places, as you know.” According to Reuters, Southgate has not yet decided on the starting lineup ahead of Monday’s World Cup opener against Tunisia. England will also face Panama and Belgium in Group G.
