after the 'dream' he was chasing at Liverpool
turned into a nightmare.

'I'm delighted to be back. This is a club that's dear to my heart and I've got some great memories from when I was here for six years,' the Republic of Ireland international told Spurs TV.
'I'm looking forward to the next few years I have with the club and I'm really delighted to be back amongst the lads again.
'I have to say, it's like I never left. The lads have been spot on, the usual, and every fan I've met so far has been absolutely brilliant to me.
'I don't think I needed convincing (to come back). For whatever reason things didn't work out for me up there. That's life. And sometimes you just have to accept that and get on with it.
'I was chasing a dream - the team I supported as a kid, as a kid growing up you always want to play for the team you support.
'But sometimes the grass is not always greener on the other side and that's been the case. I'm back now. That is the past and I am looking to the future.'
With the transfer has come a change in priorities for the 28-year-old, from fighting for the Barclays Premier League title to simply trying to ensure survival.
Spurs sit just one point above the bottom three in a congested bottom half of the table, but Keane insists his destination was only ever going to be White Hart Lane.

'There was only one choice, one thing I would come back to and that's Tottenham,' he added.
'I'm back now and I am here to get Tottenham Hotspur back up that league, because if I was not here as a player and looking at it from the outside and worst case scenario Tottenham did get relegated I would be absolutely devastated.
'I hate even speaking about relegation, looking at the squad we have, but the reality is we are there so we have to accept that and do something about it.'
