Spanish champions Real Madrid are planning a £30mn bid for Hotspur midfielder Luka Modric, according to the Daily Mail. The 26 year old, who has also been linked to Manchester United, is understood to be keen on playing Champions League football next season and the fact that Spurs failed to qualify for next season's tournament, coupled with the dismissal of manager Harry Redknapp, has thrown the Croatian international's future at White Hart Lane into doubt.

Modric has been attracting interest from Madrid for some time and the report says Los Blancos boss Jose Mourinho has now asked club chiefs to go ahead with the offer. The Croatian joined Spurs in 2008 from Dinamo Zagreb, for a fee of £16.5mn, and has gone on to make more than 150 appearances for the club in all competitions.

The Modric - Villas-Boas Dilemma:

If Modric leaves White Hart Lane, it could jeopardise the club's chances of landing Andre Villas-Boas as their next manager. The Portuguese tactician reportedly sought assurances from chairman Daniel Levy the club would not sell their best players - particularly Modric - before he committed to the job. The former Chelsea manager is a huge admirer of the Croat playmaker and tried to sign him last summer, when he was in charge at Stamford Bridge, only for Spurs to knock back a £40mn bid.

However, keeping Modric will not solve the problems at White Hart Lane.

Spurs are rumoured to be facing a massive player revolt if they appoint Villas-Boas to the job, according to The Sun. The report claims some of the club's senior players, who are already upset with Redknapp's departure, are far from impressed with the prospect of working under Villas-Boas. It appears they have spoken to players at Chelsea before arriving at their decision. The 34 year old former FC Porto manager was sacked by the Blues in March after a run of poor form and amid reports the players had lost respect for him.

The north London club is already facing a small crisis in keeping star names due to the absence of Champions League action and the exit of Redknapp - who was a players' favourite. So, if they decide to appoint Villas-Boas, there is a good chance it could lead to an exodus and Villas-Boas will have to re-build the squad again. There is every chance, however, that if they were to come to such a situation, the club will pull the plug on a deal for their first choice manager.

The Alternatives:

The other big name been linked to the Spurs managerial post has been of France coach Laurent Blanc. However, the former Bordeaux boss recently stated his intention was to remain with Les Blues unless he received an exceptional offer. As far as Spurs are concerned, if a move for the 46 year old falls through, Wigan Athletic's Roberto Martinez will emerge as a strong contender for the role.

Meanwhile, former Tottenham striker Louis Saha has praised Blanc for his work with the national team and called for him to continue with the job.

"He's a top manager. He'll always have interest. I can imagine him being in the Premier League because of his experience. I want him to stay in the job for France because he has been doing a terrific job so I wouldn't like him to go to the Premier League yet," Goal.com quoted the former Manchester United forward as saying.

Blanc took over from Raymond Domenech and has transformed the fortunes of the French national team after an embarrassing and controversial exit at the 2010 World Cup.

France face holders Spain in the quarter final of Euro 2012 in Donetsk on Saturday.
