Tottenham are reportedly set to hand Arsenal a major transfer blow as they have agreed to match West Ham United defender Winston Reid's demands in the hope of landing him in the summer.

According to the Mirror, Spurs chief Daniel Levy is keen to beat their arch rivals for their primary defender target in the ongoing January transfer window.

Arsene Wenger has been monitoring the defender's contract situation in recent months and is keen to sign him during the ongoing transfer window to ease Arsenal's defensive problems.

The north London club recently lost Mathieu Debuchy to a long-term shoulder injury and will again be short in the centre-back area as Calum Chambers, who is the only backup for Laurent Koscielny and Per Mertesacker, will be forced to fill in at right-back.

However, the French manager is unwilling to meet the Hammers' valuation of the player and reports earlier in the season suggested that the Gunners were willing to part with £4m to bring the defender to the Emirates Stadium in January

But Sam Allardyce has admitted that the club will not sell the defender unless a big offer comes in, which could tempt the club to part with the defender in January rather than lose him on a free transfer in the summer.

The east London club is aware that the player is allowed to talk to interested clubs abroad, but are also wary of clubs in England, who will turn the defender's head by agreeing to meet his demands of £60,000-a-week wages and a £1m signing fee.

Tottenham are one such club, who are willing to match his high demands and hope to come to an agreement with the player, which will see him make a summer move to White Hart Lane.
