RALF RANGNICK was frustrated that Manchester United saved one of their best performances until his final match in the Old Trafford dugout ahead of his team's trip to Albion on Saturday.

Played out to a backdrop of fan anger against the Glazer family, the final home game of a miserable season ended in a comfortable 3-0 victory against Thomas Frank’s Brentford side.

Bruno Fernandes, Ronaldo and Raphael Varane struck for United on a night Rangnick wished he could have enjoyed more often after succeeding Ole Gunnar Solskjaer at the end of last year.

The interim manager’s inability to get a consistent tune out of the squad means they are set to miss out on Champions League qualification and he admitted he was disappointed that they did not play like that more often.

“I think tonight we probably showed one of our best performances in the last six months in possession of the ball,” Rangnick said.

“We were in control of the game in most parts. We still had a few gaps defensively but in general I was pleased with the performance we showed tonight.

“The season is not yet over, we have another two games to play away at Brighton and Crystal Palace.

“We have to divide (my time) into different parts. We had very good games, very good performance to start with and in-between, the home games against West Ham, Tottenham, away at Leeds.

“But what we lacked in general was just consistency. At times we had problems to score goals.

“To start with it was important to stabilise the team and help them to concede not that many goals, but what was lacking was consistency.

“Obviously I am not completely happy with those six months. I would have expected us to qualify for Champions League.”

Old Trafford said farewell to Rangnick and midfielder Nemanja Matic on Monday, with Juan Mata and Edinson Cavani also featuring before their expected summer exits.
