Manchester United coach Ole Gunnar Solskjaer admits that building his side back to the level of the top teams in Europe will take times.

The Red Devils were knocked out of the Champions League on Tuesday as they looked to overturn a 1-0 first-leg deficit against Barcelona but succumbed to another defeat at Nou Camp to lose the quarterfinal tie 4-0 on aggregate.

The return leg saw Lionel Messi getting a brace and Philippe Coutinho netting a brilliant third as Barca set up a semi-final against Liverpool or Porto.

“I’ve said all along this isn’t going to change overnight and the next few years are going to be massive to get to the level of Barcelona.

“We’re on with the job and we’ve spoken to the players about it as well.

“We need to create an environment of top, world-class attitude every single day. We’ve got a lot of good players to work with but as I have said, we have a rebuilding job. It started with coaches, players and of course one or two additions in the summer.”
