Mourinho says his Manchester United team are ‘growing up’ but admits they need to start scoring first in more games.He said: “If we keep conceding goals before the opponent, it will arrive the day where we cannot come back. So, we have to make sure we grow up not just in our approach – because I think that is clear that the team is growing up.“But also we have to grow up in our compactness and to start matches well. Which, I have to say against Juventus, happened.”Pep Guardiola will be wary of United’s resilience already, having witnessed his City team throw away a two-goal lead to lose 3-2 to their neighbours at the Etihad in this fixture last season.He said: “Last season we lost, but every game is a new history and a new chapter. We realise how strong United are. When they dominate and create chances they win easily, but you can have the feeling you are in control and they can still punish you.“It’s Manchester United – with Liverpool, they are one of the strongest teams in England’s history. I hope it can be a good derby and we can enjoy watching it.”Romelu Lukaku could return to action for United today.The 25-year-old missed the trips to Bournemouth and Juventus with a hamstring complaint but will be assessed as the striker steps up training.City have won just two of their last eight matches against United in all competitions (D2 L4) since winning four in a row between 2013 and 2014.United, who won 3-2 at the Etihad last season despite being 0-2 down, are looking to win back to back Premier League games at the stadium for just the second time, also doing so with wins in November 2008 and April 2010.Premier League meetings between City and United have been won by the away side on 17 occasions – only Aston Villa vs Liverpool (19) and Everton vs Man Utd (18) have been won by the visiting team more.United have conceded 18 goals in their 11 Premier League games this season.
