The Red Devils came from behind to claim a draw at the Hawthorns but their manager believes that only individual errors cost his side as they tested yet another new system

Louis van Gaal felt Manchester United produced their best performance of the season in Monday night's 2-2 draw with West Brom.

The Red Devils were twice forced to come from behind at the Hawthorns and only earned a point thanks to a sublime, side-footed strike from Daley Blind with just three minutes remaining.

Van Gaal, though, felt that United had played their best football of the 2014-15 campaign to date and was thus bitterly frustrated that the visitors had failed to secure the win that would have propelled them back into fourth place in the Premier league.

"I'm very disappointed because we played our best match of the season and the result is not good enough," the former Netherlands boss told daviduf007 at Sky Sports.

"I have to also be happy because we created a lot of chances and only two shots from West Brom were goals.

"We gave it away because of our individual errors. That's a pity because you can give a new start when you win here, and that was possible I think."

Van Gaal opted to play Robin van Persie in a lone striker's role within a 4-2-3-1 system, with the change in formation the second alteration the veteran coach has made since originally opting to play 3-5-2 at the start of the season.

And he believes that his players are able to adapt to the new philosophy given their dominance at the Hawthorns.

"I'm looking for balance and maybe with this formation, but with the same philosophy, we could do better," the Dutchman mused. "I've seen in the training sessions that we are better now. 

"The players understand the philosophy more with this formation. And I've seen it again today and that's why it's such a pity that they don't have the result they deserve."

Asked whether the formation could trouble Chelsea in their next game, he added: "You never know but I have a lot of confidence."
