Oxford United are dark horses for promotion, according to Charlton boss Karl Robinson.

The Addicks travel to the Kassam Stadium tonight with both clubs occupying a play-off spot.

U’s manager Pep Clotet has won six of his 13 league games while implementing an attractive brand of football.

And Robinson is not surprised by their strong start to the season.

He told Valley Pass: “I’ve really enjoyed watching Oxford play building up to this one, they play with a freedom, energy, wingers and get in your face.

“I said at the start of this season that I thought Oxford would be a dark horse to push on because they have a really good manager, and assistant coach Derek Fazackerley has been there and done it.

“They’ve got some really good players right the way through the team but they have weaknesses - as we all do. It’s about us getting it right.”

Clotet, 40, landed his first managerial job in English football after being appointed by Oxford in the summer.

He has been an assistant coach to Garry Monk at Swansea and Leeds in the Premier League and Championship.

Robinson says Clotet’s decision to boss Oxford proves how strong League One is this season.

He added: “It shows that people from the continent see our third tier as an opportunity.

“The third tier across the world wouldn’t get the same attendances, desire and attention to detail as we get here.

“We’re very fortunate to have that here and that’s forgotten sometimes, and when you get someone of Pep’s quality in the third tier it shows you how well thought of our game is.”
