To assume that just because both these players have a bit of skill about them that they will be a top player is a little bit short sighted. Around a decade ago or just under we had 3 of the top talents in Europe. Lukaku, barkley and deloufeu. All 3 of which were getting very good numbers, much better than Gordon did last season. But only 1 of these players actually developed and that is lukaku and he still failed at man utd and chelsea since. Deulofeu has been on a steady decline at clubs and last time I checked warms the bench at udinese and barkley has never got off the bench at Chelsea and has played a handful of games in the last season.
Now with Gordon he's scored about 3 or 4 goals in the prem and only 1 of which wasn't a deflection. He shows glimpses of good pace and dribbling skills but I would not say he looks as effectively explosive as deulofeu did. I would be interested to know what in your opinion makes you think Gordon will definitely be a top player. As I see it he has more of a chance of stagnating like most young talents do instead of progressing into a world beater.
Havent two of the three gone on to win major trophies. I was never really a big fan of Del myself.
Couldn't you throw Wayne Rooney into the mix to - there is litany of players who have left Everton for other clubs and gone on to be very successful at other clubs.
I dont understand the point you are making - players have left us and in your opinion haven't been successful - despite 100s of millions in fees changing hands and winning trophies - therefore everyone who is talented at Everton will leave and not be successful, i dont think thats a very good pathway to be judging potential player retention on mate.
Ive posted reams above on why i think hes quality mate - just this morning - but obviously we are all fallible here as we arent involved in the game - but i refer to the market - its red hot for the lid, why? - what have Bayern, Spurs, Newcastle and Chelsea seen that disproves your opinion - your putting your chips down on you being a better judge of a player then scouting Depts of CL winning clubs - would that not give you pause for thought?
