Tottenham Hotspur are considering a move in re-signing their former defender Steven Caulker in the summer, according to the Mirror.
The England international completed his move to Cardiff City last summer. He has started in 31 games for the Welsh outfit this season and is the first choice centre-back at the club.
The 22-year-old came up through the ranks of the north London club's youth system, before breaking into the first team in 2009.
However, he was unable to cement a place in Spurs' starting lineup, which saw him spend few season on-loans at Yeovil Town, Bristol City and Swansea City.
Spurs' former boss Andre Villas-Boas sanctioned the sale of Caulker to Cardiff last summer after he was considered as surplus to requirements. The White Harte Lane club's current manager Tim Sherwood is eyeing to re-sign the player at the end of the season, if Cardiff gets relegated to the Championship.
Ole Gunnar Solskjaer's side are struggling in the league as they sit in the 19th place, with 25 points from 31 games. Cardiff are level on points with 18th place Sunderland, who still have two games in hand.
The Welsh side are struggling in the top flight English football. Failing to finish above 18th place at the end of the season could then see Spurs taking advantage of the situation in making an approach for Caulker.
The north London club's manager earlier heaped praise for the centre-back's performance with his current employers and hinted that he would have never allowed him to leave Spurs.
"He wanted game time and more than the previous manager would guarantee him The club decided they would let the player go and they think they had a good deal. It is up to Steven to build on that and prove the club were wrong to let him go," Sherwood said.
"He wanted to go and play. The only thing I could have done is say 'you will play more football'. We are happy with the squad we have got and the club made the decision to let him go. It happens."
Meanwhile, Spurs could face competition from Liverpool in re-signing Caulker. The England defender has worked with Brendan Rodgers at the Liberty Stadium while he was on-loan at Swansea City.
The Northern Irishman is also believed to be interested in signing Caulker at the end of the season, as he is focusing on strengthening Liverpool's squad in the summer.
