Forestieri or Fabbrini?

I attended Saturdays friendly which saw Watford record a 2-0 win over Granada, in which Diego Fabbrini was partnered up front with Troy Deeney. I noticed, Fabbrini is not actually a striker, but a no. 10 that plays between the lines looking to receive the ball to his feet and create chances for others - a very similar job to that of Forestieri. This got me thinking, since they both perform similar roles dropping between the lines, creating space for others and linking play they most likely cannot play together as there will be know runs in behind defences.

Not only that, from what we have seen, is the best partnership: Forestieri/Acuna, Fabbrini/Deeney etc.? Despite the fact we have them both, it is probable that Zola can only play one in the system, with one vacating for the other.

Gianfranco hinted at this when speaking to the BBC: "When you have the ability of Fabbrini it's just about fitting him into the system" before stating "He does more or less what Fernando Forestieri does. They both play the position very well."

Which would you rather have starting and who would you pair them with?
