Brentford boss Uwe Rosler hopes midfielder Harry Forrester knows it makes good career sense to stick with the Bees.

The 21-year-old has found his feet in the starting line-up at Griffin Park this term having battled with fitness issues all last season following a summer move from Aston Villa.

Forrester, who is out of the contract at the end of season, has been attracting admiration for his recent performances, including his part in Saturday’s last-gasp 3-2 win over MK Dons.

The transfer window opens in less than three weeks’ time and Rosler already knows he has a fight on his hands to keep hold of his best players as he goes in search of League One promotion this term.

And Forrester is one he hopes to pin down to a new long-term deal within the next fortnight – because the youngster’s career depends on it.

“Harry Forrester is a tremendous player. He is rising to the occasion and is a big game player,” said Rosler on Saturday.

“He is thriving with the attention he gets from the crowd. But I think Harry has a lot to learn.

“We speak to him day in, day out to make the right decision and stay with us.

“I really hope he realises what he has with us. Because his career in men’s football started just three months ago and he has only played 17 games from the start. He is not the finished article.

“I told Harry he has to make the biggest decision in his football career. When you get it right you have no limit.

“When you get it wrong that can backfire big time. Which way he goes will be decided in the next one or two weeks.”

Forrester could do worse than take a leaf out of Clayton Donaldson’s book after the striker’s match-winning double proved he has grown accustomed to life in League One, according to Rosler.

The 28-year-old, below, was far from a fans’ favourite last term as he struggled to hit the prolific goalscoring of his spell at Crewe Alexandra.

His 89th minute winner at the weekend – coupled with his side’s opening strike – took his tally to 13 for the current campaign – five of which have come in his past four games.

It crowned a thrilling comeback from 2-1 down that Rosler believed was always likely.

“Coming from League Two, Clayton totally changed his routine and professionalism,” he added.

“He is now a 24/7 pro, and this allows him to manage the physical demands to play at such a high level week in, week out. He is scoring goals regularly and contributing to the team. I can’t ask for more.

“I never doubted we would come back. The tempo we set was great for 90 minutes.

“I would have taken a point to be honest, but three is even better.

“We played against probably the best ‘playing’ side in the division, but any time you put MK Dons under pressure then you have a chance.

“The big difference between the sides was fitness. We stood up and went in their face all day long.”

Brentford travel to promotion rivals Notts County tomorrow, having suffered only two defeats in their past 19 league and cup encounters.

“They are a better footballing side than last year, but we will give it our best shot,” he added.

“We are in a rich vein of form. Our spirit and belief carries us through difficult periods. I can’t wait.”
