Tottenham Hotspur have stepped up their interest in Crystal Palace winger Yannick Bolasie, according to the Mirror.

The report states that the north London club are set to put in bids for the winger after agreeing a fee with Villareal for the transfer of Roberto Soldado this summer.

The striker failed to live up to expectations in north London and Spurs are looking to add more ammunition to their squad to challenge for a place in the top four in the upcoming campaign.

Eagles chief Steve Parish is reportedly willing to listen to offers for Dwight Gayle, Joe Ledley, Barry Bannan and Mike Jedinak to cover for a massive spending spree this summer. However, they are unwilling to part with their star player Bolasie but a bid in the range of £25m ($39m) should be enough to bring the Congo international to White Hart Lane.

The winger made 34 appearances for the Eagles last season, scoring four goals and making six assists, a tally which is likely to increase with an improvement in quality across the length of the pitch.

Spurs finished the season in fifth spot and need some serious infusion of talent to go hand in hand with the usual suspects in the top four and Liverpool, who have made seven quality transfers this season.

Tottenham have signed Toby Alderweireld from Atletico Madrid, Kevin Wimmer from Cologne and Kieren Trippier from Burnley thus far this season, while allowing sixteen players from their first team and youth setup to leave the club on loan or a permanent transfer.

Meanwhile, Tottenham are close to securing a deal for Lyon striker Clinton Njie after the 21-year-old posted a premature message on Instagram, confirming the move. The Telegraph reports that the deal is set to be worth an initial £10m ($15.6m) with a further £2m in add-ons to facilitate the transfer.
