Manchester United captain Nemanja Vidic has called on his teammates to build on his side's impressive display against Champions League rivals Shakhtar Donetsk.
The Red Devils managed to come away from the Donbass Arena with a point - something no other English club has managed to do in the Champions League.
Vidic, who came back into the side after being rested for United's defeat to West Brom last Saturday, admitted his delight at earning a hard-fought point against the Ukrainian champions.
Speaking to MUTV, Vidic said on last night's 1-1 draw: "The most important thing is I saw improvement.
"I saw solidity, I saw a reaction from the last game. We were hard to beat in all positions, not just at the back, but in midfield and wide, and that's the way we have to play.
"We have to work hard, play as a team and hopefully goals will come.
"We improved, we didn't let them have many chances to run at our defence. Our team worked really hard but there is still room to improve, and that's a good thing.
"We know we have not played at our best yet, but we still have time to improve and the next game is really important."
United took the lead in the 18th minute but were pegged back in the 76th minute through Brazilian winger Taison.
Despite Taison's equaliser, Vidic believes David Moyes' side should take great encouragement from their performance.
"We came to win, we wanted three points but we have to accept as well they were a good team," added the Serb.
"They have quality players and it's hard to play away in the Champions League, but we had some improvement on the last game.
"That's encouraging and we showed character from what happened in the last game, and hopefully we can improve against Sunderland."
Manchester United currently sit level on points with Shakhtar Donetsk at the top of Group A, having won their first game against Bayer Leverkusen.
Moyes' side face Spanish side Real Sociedad in their next two Champions League games.
