One of the main reasons and this is already known, is that Antony has rediscovered his extraordinary form at Real Betis. He also enjoys the full love and support of the club fans and management and the sense of comfort and togetherness he feels is crucial. While Real Betis may not be competing for major trophies right now, the environment is clearly a good fit for Antony. If he feels valued and can make a meaningful contribution, continuing his journey with Betis won't be a setback; it could be the perfect place for him to develop.
Not just the discovery but the love , the atmosphere, the feel of relevance and the chemistry between his team mates and the coach is another key factor that is doing him more good at Betis than he got at Manchester United. And thisbis going to give him a good boost in his career and help him get more career achievements. I wish him the very best.
