The Whites were in control from start to finish, enjoying 75 per cent of the possession and scoring four goals in the first half.

West Brom barely laid a glove on Bielsa's men, but they still had to beat what was in front of them being ruthless in front of goal helped them pick up a second win in three days.

A disastrous own goal from Romaine Sawyers kicked things off at the Hawthorns and after that it was a painful night for the hosts as Gjanni Alioski, Jack Harrison, Rodrigo and Raphinha all hit the net.

"The team was very efficient," said the Argentine.

"We made eight chances and managed to score five goals, even if one of the goals wasn't through us."

"Normally from eight chances we score two goals maximum. So with such a high efficiency, the margin of the win was higher. Apart from that I think we defended well the whole game. We didn't commit any avoidable errors."

There were impressive performances all over the pitch, from back to front, but Stuart Dallas came in for praise from his head coach, having popped up almost everywhere.

"It really did look like he was in many places of the pitch constantly,"said Bielsa.

"In the positions or places where he acted, he didn't commit any errors."

With the victory Leeds moved onto 23 points from 16 games and now hold a 15-point lead over the side they beat tonight. They sit 11th, three points off sixth placed Chelsea and have brought their goal difference back to zero.

Bielsa expects tough challenges ahead, however, before they can call themselves an established top flight side.

"Every game in this league is a challenge because all the teams have secrets, capacities, they're all a different challenge," he said.

"There are few games you can think of that there are very few difficulties to resolve.

"For us well we've only been in this league for 16 games and there are still many challenges and many tests we have to pass before we can say we belong."
