I get the idea here but it isnt that simple. At Madrid he should have been a club legend and instead he was constantly whislted and jeered by fans. He would be loved here so it may be different.Bale would effectively be like repeating the Walcott deal imo. Hasn’t been that interested in club football for a while now and if you can’t be interested at Real Madrid you aren’t going to be interested at Southampton
Also, some have said he isnt the player he was. Which is of course true, but we are competing for 10th in the Premier League, up against Palace & Villa. We aren't competing to win the Champions league 5 times in 9 years. He doesnt need to be as good as he was.
