Tottenham Hotspur manager Tim Sherwood has warned Mauricio Pochettino that it wouldn't be easy for him if he were to take over at White Hart Lane.
Pochettino has made a great impression at Southampton in a year, since taking over from Nigel Adkins.The Argentinian manager has influenced a very attractive style of football at St Marys and has led the club to ninth in the Premier League this season so far.
However, speculation has mounted in the last week over the former Espanyol manager's future in the wake of the resignation by chairman Nicola Cortese.
The 41-year-old has committed his immediate future to the Saints but he admitted he didn't know whether he would still be in charge next summer.
Uncertainty surrounding the manager has led to links to other clubs and Spurs are one of those.
Sherwood has impressed since taking over from Andre Villas-Boas who has sacked in December. Initially he was employed on a temporary basis, but positive results led to Sherwood, who spent four years as a player with the club, being given an 18-month contract.
Despite his early success with the club who lie sixth in the Premier League currently, the 44-year-old admits that Pochettino could be a threat to him.
"I am realistic enough to know the ambitions of this club are very, very high and the demands are high," said Sherwood.
"I knew that before I took the job and I am just hoping I can do enough to keep the job in the long term.If the results meet the expectation of the club, I will still be here. If they don't, I won't be. At the moment it is going all right, especially in the league. Long may that continue and, if it does, it will be hard for somebody to come in here and push me out of the seat."
Sherwood, though, insisted Pochettino would find it tougher in London than on the south coast.
"The expectation at this club is far greater than they have at Southampton." He continued
"We were talking about that last week on the development side and used [Andros] Townsend as an example. If he was at Southampton he would not have had nine loans – he would have had his development through the leagues there, League One and so on, like [Alex] Oxlade-Chamberlain and Theo [Walcott]. That is the market they are in.
The two managers have already gone head-to-head this season and the result went Sherwood's way; winning 3-2 at St Marys.
