Brentford boss Mark Warburton says he will only add more players to his squad if they are good enough.
The Bees hit their pre-season straps on Tuesday night with a 5-1 win over Barnet, thanks to goals from Stuart Dallas, Alan Judge (2), Andre Gray and Montell Moore.
The match featured an appearance by former Cardiff City and QPR 34-year-old Tommy Smith, who is on trial at Griffin Park following his release from the Bluebirds in the summer.
Warburton was delighted with his side's attacking threat at Underhill and was impressed with the contributions of new signings Alex Pritchard and Scott Hogan.
And he admitted he would only make a move for Smith or anyone else for the right reasons.
"Offensively we were very strong and in truth - in a very respectful way - that could have been a lot more," he said.
"All round the whole squad showed some excellent quality.
"Scott's a good player. His first touch was sublime. He showed his strength and speed.
"Add that to Andre's pace and Moses on the far side, who has blistering pace, and we now have some new weaponry for the level up.
"If we do business - maybe one or two more - we'll do that to add quality. There is no point adding bodies for the sake of it.
"The squad is shaping up well. We have to make sure whoever comes in is in a key position and adds value.
He added: "Tommy [Smith] is a high quality player and a great professional on and off the pitch. He adds real quality.
"He has been there and done it. He's played at the highest level in the Championship, won promotion to the Premier League and playeed there.
"He's a class act. We'll see how we go, stay in contact and see where it takes us."
Brentford's friendly with Espanyol next Wednesday has been cancelled and the Bees will instead play Spanish side CA Osasuna at Griffin Park on Tuesday night.
