During his loan spell with the Bees last season, the Spaniard was used as a wide player but did play through the middle against Fulham in the second half.
Lasse Vibe has impressed in his last two home games playing as the main striker and there is a belief at the club that he can replace the departed Scott Hogan .
“I was willing him on to get his hat trick which would have been poetic," Smith said.
"His non stop running and closing down was brilliant. As a team, our pressing was what we want it to be.
"I also have Philipp Hofmann.
"If you remember Sergi Canos' last home game, he played up front against Fulham and caused a lot of problems.
"Florian (Jozefzoon) is going to be a goal threat.
"Sergi is a goal threat and Jota is a goal threat.”
Brentford fans are unhappy that a striker wasn't added after Hogan's inevitable departure but Smith insisted there wasn't the right player available at the right price.
He added: “January, for me, has no value in the window. People are paying crazy money.
“We might have got a lot of money with Scott.
"We're not an Aston Villa or Sheffield Wednesday so we have to be more astute in the market.
"I'm pleased we signed Sergi and got Florian as well.
“The value is the important thing and nobody came to the fore that was of value for us.
”Smith changed from the 3-5-2 formation deployed in recent weeks and played a 4-3-3 with Jota and Jozefzoon on the wings and the move paid off as Aston Villa were put to the sword.
“We haven't had wide players in abundance. Flo has come in and Jota has come back.
"I wanted to flip the system but we haven't had the opportunity to.
“John Egan had 21 stitches in his ear but he wanted to play and I had to make a decision.
"I said to the owner the other week I fancy flipping against Villa. It worked out and it's great to have the opportunity.”
