Leeds' feet firmly on the ground despite dream start, says Marsch

Leeds convincingly beat Chelsea 3-0 last weekend to move up to third -- two points behind leaders Arsenal -- a position they will have to get used to after narrowly escaping relegation last season following Marsch's arrival in March.

They also beat Yorkshire neighbours Barnsley 3-1 on Wednesday to move into the third round of the League Cup.

"I don't think we needed validation internally. Something special has been happening here for some time," Marsch told reporters on Thursday ahead of Saturday's trip to Brighton & Hove Albion.

"The results always help. Before the (League Cup) game I said, 'Shut the door on that result because it does not mean anything next week'.

"We're continuing to commit to the style, the mentality of the group, the engagement -- everything. Because the minute you think you are doing well, you get smacked in the face."

Marsch praised their 21 million pounds ($24.79 million) signing Luis Sinisterra after he scored in Wednesday's win and the American coach said he expects the Colombian winger to have a "huge impact" this season.

"We knew we had a fantastic player," he added. "I'm not surprised he was man of the match. We think very, very highly of him.

"The most important thing is the players are improving internally. Other players see how good you are and what you can bring."

Marsch also said Leeds are looking to sign another striker but could not commit to new signings yet.

"How likely it is, that's dependent on how things play out and what their availability is," he said.

"We don't have a surplus of money to bring in a huge transfer but we've done a good job of analysing players who are of interest to us."
