The Spurs manager, who has spoken highly of Carroll in the past, told reporters that the 21-year-old could have been the player to make the difference for Tottenham this season and even compared the youngster to Luca Modric.
'I could go on for ever about this, it’s just about having a blend in different areas of the field and different types of players in different areas of the field, and I just think the squad misses that a little bit,' Sherwood told reporters.
'Sometimes you can turn around and look to make a change, and it’s not always a like-for-like change that you want to make.
'But we miss that player - I’m not saying [Mousa] Dembele can’t do it because he can pick it up and he can dribble – but we miss someone who moves that ball and passes it between the lines very quickly, and he assists the assister.
'Gareth Bale needed that ball very quickly and I think Luka Modric got it to him very quickly. I think Tom Carroll was that player - he can do that, absolutely. I tried to bring Tom back [in January], it just wasn’t possible.'
The pint-sized midfielder is spoken highly of for his tidy technique on the ball and eye for a pass, but as of yet he hasn't impressed the supporters of clubs he has been on loan to.
Whilst on loan to Derby County under the management of Nigel Clough, the current Tottenham Hotspur manager spoke very highly of the young star and even suggested that one day he play for Barcelona. Nevertheless, his loan spell at Derby was incredibly underwhelming and the Rams supporters were left scratching their head at why the teenager was so highly-rated.
The England under-21 international comes across as a player who doesn't make much impact on the game, especially when he hasn't got the ball. For instance, he isn't a player that necessarily likes to track back, or put his foot in where it hurts. Two traits which, in my opinion, are vital if he is to become a Premier League player in the future.
For Tom Carroll now, it's a case of looking at the career of Adam Smith, a former Spurs player who was highly-rated but suffered multiple loan flops, and not going down the same route.
Judging by the QPR fans reaction of Sherwood's comments it seems the midfielder has once again been underwhelming this season, although he does have the play-offs to become an instant backpage hero.
In a thread titled: 'I wish he was missing from our midfield Tim' and 'Tom Carroll' I have picked through the posts to find some of the more interesting view points for Rangers fans.
'Someone please, please enlighten me as to why he is so highly regarded by Redknapp? One of the most infuriating players of the season. Absolutely no physical presence, no vision on the ball and an embarrassing reluctance to get stuck in. At times it's like watching a 12 year-old run around aimlessly in the centre of the pitch. One moment yesterday summed him up: receives the ball in a decent position on the left flank and then slices it into the stand like a Sunday League player. He is just shocking. Start him in the play-offs and we'll just get overrun in midfield. What on earth does the old toad see in him? Could it be a dodgy 'arrangement' with Spurs I wonder? I just can't understand how he is the first name on the team sheet every week.'
'What is most irritating about him, other than the constant misplaced passes, is his habit of slowing every attacking move down. There was one moment yesterday in the second half when he received the ball in space on the right-hand side with Austin and Morrison charging forward. What did he do? Yep, turned round and passed it sideways...'
'I know exact time your talking about I went berserk. Two options of putting the ball over the top and it was two on one but he played safe and that's his problem. He also has an uncanny nack of letting players run straight past him without making any real effort to stay with them.'
'The weakest link in the team is Dunne and Carroll. Get rid of them an we'll be solid.'
'nail on the head! this is what frustrates me most about the lad. Even when he has room to run forward with the ball, he's always turning and looking for the pass.'
'I wish he was missing from our midfield Tim!
