Barcelona defender Gerard Pique has warned his team mates against complacency following their 1-0 win over Manchester United in the Champions League quarter final first leg.
An own goal from Luke Shaw gives the La Liga leaders a slim advantage ahead of the reverse fixture in the Nou Camp next week, and the Catalan centre back said his side will be paying United the upmost respect.
"It is always very difficult to come and play here and particularly to win.
"We have seen the situation with United against PSG in the previous round.
"They had a bigger advantage and look what happened."
The 32 year-old returned to Old Trafford for the first time since he returned to Barcelona, in 2008, and he praised his side's resilience against Ole Gunnar Solskjaer's side.
"Scoring an early goal settled us and gave us peace of mind.
"We performed well in the first half, and when our chance came along, we took it, and that is the most important thing."
Pique is likely to be rested this weekend, as Barcelona face Huesca, to keep him fresh for the second leg – and he is confident about his role in the season run in.
"Defensively we are in the best form of the season right now.
"I have more than enough energy to help the side keep going."
