Antony told the club's website: "It's certainly been an excellent season for Garnacho.
"He's still a very young lad and full credit to him for his performances. I'm really happy for him and hope he continues doing what he knows how to do with a focused mind and continues helping us marking, making passes and running for the team."
"I'm really pleased for them," he continued. "Willy (Kambwala) is really hard-working, always training hard and I'm delighted with the game he had against Liverpool (the 2-2 draw in the Premier League).
"He had a great game and I congratulated him afterwards.
"Kobbie has had a longer run of games," Antony continued. "He's a huge talent. I see so much talent there and I'm really happy for his performances.
"I've been in the position of these young players although I'm still only 24, I was also playing at their age as well. With their talent, together with focus, a supportive family and looking after themselves, things will happen naturally for them."
