Tottenham manager Mauricio Pochettino insists Kyle Walker's injury problem is not too serious.

The England right-back left Turf Moor on crutches after clashing with Kieran Trippier just before half-time of the 0-0 draw with Burnley with what appeared to a foot injury.

However, Pochettino has played down the gravity of the situation by saying his full-back is ok.

"We expect and we hope that it's not a big issue," he said.

Sixth-placed Spurs host Aston Villa next Saturday and will need Walker fit as they desperately need a victory to keep alive their Champions League hopes.
