Aaron Ramsey claims Gareth Bale has gotten even better since Andre Villas-Boas took over Tottenham, with the Arsenal star admitting the winger has become unplayable as he continues to keep his side in the top four with match-winning performances.
Bale scored a brace in Spurs' most recent win over Lyon in the Europa League, and the side are currently four points above Arsenal in the table in what looks set to be a tough fight for a Champions League spot.
And Ramsey, who is looking to take the Gunners back into contention for Europe's premier tournament, believes that Villas-Boas's decision to reposition the star has been to his benefit.
"As soon as they moved Bale up the pitch, he has been unplayable," he told The Mirror.
"When Bale first started at Tottenham they were struggling to win whenever he played at left-back, but it is unbelievable how quickly things can change in football.
On Bale's brace against Lyon, he said: "Those free kicks he produced against Lyon on Thursday - I've seen how he does it when we stay behind after training with Wales. He stays behind and practices them and it has paid off for him."
Tottenham and Arsenal play one another on 3 March, and the match could eventually decide who takes a top four place at the end of the season.
Spurs had mixed success during the January transfer window, landing Lewis Holtby but missing out on a striker in the face of injury problems for Jermain Defoe.
The emergence of Bale over the last couple of months couldn't have come at a better time for Villas-Boas, who has taken full advantage of the Wales international's skills to make a serious claim for a Champions League spot.
