Brentford sporting director Mark Warburton said the departure of Harry Forrester underlined the club’s desire to only want players committed to the Bees cause.

Forrester who rejected a new deal at Brentford, confirmed his exit to Doncaster Rovers this week after his Bees contract expired on Sunday, with the two clubs still negotiating a compensation fee.

Warburton said: “While we are sorry to see Harry depart, it simply underlines the fact that while we will move to attract and secure talented individuals, we only want players absolutely committed to Brentford FC.

“We will make very positive and aggressive offers to retain the services of key staff, but not seek to break the pay structures that we think are appropriate.”

Meanwhile, Brentford boss Uwe Rosler may not be too concerned over results during pre-season, but defender Harlee Dean believes winning is the only way to erase the memory of Wembley heartache.

The Bees opened their tour to Germany with a 3-0 triumph over FC Einheit Rudolstadt on Tuesday, thanks to goals from Clayton Donaldson, new boy George Saville and Paul Hayes.

It was the team’s first outing since the 2-1 League One play-off final defeat to Yeovil Town.

Dean netted his side’s only goal as the Bees missed out on promotion for a second time at Wembley in May, having failed to beat Forrester’s new club Rovers at Griffin Park in dramatic circumstances on the final day of the regular season.

Club captain Kevin O’Connor hopes the pain of defeat can inspire an automatic promotion bid this time around.

And Dean, who is nursing an achilles problem through pre-season, has admitted the fear of failing again was driving him this term.

“You have to keep that hurt in you because it will make you never want to feel that again,” he said ahead of Saturday’s friendly with Bundesliga Three side Rot- Weiss Erfurt.

“I am looking forward to trying to just get back in to games and forget about Wembley.

“I just want to get back to the league and get back to winning, because football has some bad memories for me and I need to get rid of them.

“If pre-season can help me do that as well then I am looking forward to it.”

O’Connor, starting his 15th season at Griffin Park this year, said: “You have to use last season to inspire you and push you to make sure that doesn’t happen again.”

Forrester’s departure has been tempered by the new arrivals of Swindon Town captain Alan McCormack, Watford keeper Jack Bonham, Chelsea loan star Saville and Walsall hot shot Will Grigg.

All four new boys got a run out in midweek and, while Griffin Park chief Rosler, who has also signed Everton defender Jake Bidwell on a permanent deal this summer, was a little disappointed with his side’s wayward finishing, he believed the result was not the be all and end all.

“This is a conditioning training camp, not a playing training camp. The focus is to get the basics right for the whole season,” he said.

“We are not focusing on results, but of course every time we play we want to win.

“It is more important we come through the heavy schedule we have planned and come through with no injuries.”
