Former Real Madrid defender Michel Salgado believes that the Spanish giants would be 'crazy' to spend the same amount of money on Dele Alli as they did on winger Gareth Bale.
Alli has been in great form for Tottenham since making his debut against Manchester United in August 2015 and he has attracted plenty of interest from some of Europe's top clubs, including the La Liga leaders.
The Spurs midfielder, who received his first red card of his professional career on Thursday against Gent as his side crashed out of the Europa League, has proven himself as both a goalscoring and creative threat under Mauricio Pochettino.
