Goalkeeper Sergio Romero believes interim coach Ole Gunnar Solskjaer has boosted Manchester United’s confidence and brought back a “certain happiness”

Since his appointment last month at Old Trafford, Solskjaer has gone on to match the legendary Sir Matt Busby’s record of winning all five of his opening games.

Aside from that, United have also returned to their usual style of attacking football after deploying a rather conservative and unattractive style of football under former manager Jose Mourinho.

And Romero believes that the results achieved under Solskjaer have given United a new-found level of confidence as they look to end the season with a top-four finish in the Premier League.

“We’ve had a great run,” Romero told the club website .

Howe: Bournemouth deserved to win

Bournemouth manager Eddie Howe has praised his side's discipline and hard work after their 2-0 home win against West Ham on Saturday. Howe was impressed...

“Not just the results, but the way in which we have won the games as well. Scoring five goals in one match was a big boost to confidence and was really something.

“What we’re showing now, after a great Christmas, is only right for a club of this stature, [it] proves what we can do. The run we’ve had over Christmas and the new year is a testament to that.”

Romero added: “[The manager] knows what he wants to achieve – both for the club and us as individuals. On the pitch and within the club, he has made it very clear from the outset so we know the expectation of us inside the club and externally.

“You can see he has brought to the club a certain happiness and it is going well.”

The Red Devils will take on Tottenham on Sunday at Wembley in the Premier League.
