Indeed, Frank believes Gray has the potential to match the success of Manchester City midfielder Rodri.
"Let's put it this way, yes we spoke with him, but he ended up at Tottenham and maybe that was good because I still have the chance to work with him!" admitted Frank.
"It’s one of those things. No matter where you are and what club you’re in, sometimes you go for targets and you can’t make it for whatever reason.
"What I am happy with is what I see from Archie here and I believe he’s got a big future ahead.
"I see him as a midfielder who can play six or eight. That is his position and these days midfielders need to be more complete. You need to be a little bit of a six, a little bit of eight and 10 and two of the best in the world right now are probably Rodri and Declan Rice.
"They can do a little bit of everything. I see Archie, and they are big names to compare him to, but I see he has got the same potential."
