Id take bale in a heartbeat, writing him off after a 15 minute cameo is... unwise. It took us 4 games to get any real performance out of the team after the time off, you cant expect him to come in and score a bicycle kick hattrick on his debut.
Clearly lots of the so called pundits have not seen Bale since 2013. Maybe except a few CL finals. He is nowhere near the player he was last time he was in PL. People hyping up Tottenham front 3 Kane, Son and Bale... Bale is pretty crap if you ask me.
The only doubt I have for him is actually Jose's way he might utilise him.
Mourinho sometimes likes the tactic of having a winger on one side who stays closer to the touchline and aims a cross to a striker like Kane. Kane is look very creative now so Son and Bale cutting on either side could/should work. Bale can also play CAM/SS like he does for Wales. He was that speedy LW when he left spurs (I actually think that was always his best position than RW because he looked more fluid there) but he might not have the speed to play such a position anymore.
I enjoy watching Bale play and hope he gets to a useful standard when I have a neutral type of mind as he is one of my favourite players of the last generation. I personally dont see him as this Sanchez type player who came with high expectations and fell I'm nearly every single way. Bale is at home, he doesnt have wonder expectations and as long as he is tactically made to play well then I dont see why he shouldn't be better than Berjwijn or Lucas Moura for example.
