Spurs are currently caught between a rock and a hard place.
They have performed outstanding over the past two seasons and IMO been the best side in the country over that period. However, they have fuck all to show for it and the obvious way to address the problem will have a huge impact on their finances.
In a similar manner to us, Spurs lack that winning mentality to drag them over the line. Addressing that issue does not come cheap and whilst we are looking to add the likes of Alves, Sanchez and Mendy (all players with league titles to their CV) to the already signed Silva and Ederson (League winners), they are after the likes of Barkley.
It is going to be extremely difficult for Spurs to sign the calibre of players needed to kick them onto the next level without boosting the wages of Kane, Walker and Erikson in the process.
The Semi-Final of the FA cup really highlighted the short-comings of some of the teams in the PL. Spurs' mentality was badly exposed by an under-strength Chelsea side who just know how to get over the edge. Us against Arsenal was a game of two sides who lack any sort of ruthlessness and was ultimately dominated by Yaya and Sanchez. Unfortunately for us, Sanchez came out on top that day.
You can hardly blame Walker for wanted to come to a side who are efficiently eradicating their issues and offering a higher wage, rather than stay at a club who seem to lack that ambition.
