Brentford boss Uwe Rosler paid tribute to Clayton Donaldson after the striker hit both goals in a 2-0 victory at Oldham.

Donaldson struck early and late at Boundary Park, handing the Bees' promotion drive another boost and taking his personal tally to 17 goals this season. The ex-Crewe and Hibernian frontman gave his side a fifth-minute lead when he met Harry Forrester's left-wing cross with a powerful header from eight yards.

Oldham - who shocked Nottingham Forest in the FA Cup last week - created half-chances, but Matt Smith, Jose Baxter and Cliff Byrne failed to seriously test visiting keeper Simon Moore.

Marcelo Trotta wasted a chance to double Brentford's advantage before Donaldson pounced again on 82 minutes, slotting in from 12 yards after a pass from Sam Saunders.

Rosler said: "Clayton is one of the best in this division. There are a few good strikers around, but he has been very consistent for the last 18 months in what he contributes to the team. They had momentum without creating big chances, but after we put Jonathan Douglas into the holding midfield position we were the side with more possession.

"This was a tricky game. Oldham blow hot and cold and they have lost some home games, but they beat Forest last week. The longer the game went on, the more you could see our quality. But we shouldn't be looking at the league table - we have to concentrate on performances."

The result means Brentford are unbeaten in 13 league games, but struggling Oldham have taken just one point from six matches.

Latics manager Paul Dickov said: "That was really disappointing after what happened in the cup last week. We know Brentford are a good team who are up there, but we were lacklustre with and without the ball.

"It was a nearly game for us and we could have got something out of it with an extra 10 per cent to our performance. We have to show the same effort and desire in every game but, with the way we played, I couldn't really see us winning.

"Compared to Brentford we were a bit lightweight in midfield and I'll be looking to bring people into the club if possible."
