Watkins' frustrations also come from the fact that he is closing in on a record for Aston Villa. The 29-year-old is one goal away from matching Gabby Agbonlohor's 74 Premier League goals.
He added: "Am I aware of the record? Of course I am. That is why I wanted to take the penalty as well. To equal it, then one more to get the record. Two more to beat it. I am thinking of breaking it. I will do it at some point and I’m looking forward to that day."
