Celtic are well and truly in the groove again.

After a topsy-turvy few weeks leading up to the international break, Neil Lennon's side have shown their ability to bounce back and continue fighting.

Their 5-0 win over Ross County last weekend was evidence of a side who are in no mood to surrender the title to Rangers.

They have two games in hand but are looking mightily impressive.

What's more, their new signings have settled in instantly. Albian Ajeti has three goals in three matches while Brighton loanee Shane Duffy scored on his debut too. 

Nick Hammond will currently have a beaming smile on his face - he has done shrewd work in the market and it's already beginning to pay off.

However, it's important not to judge Celtic entirely at the moment. Unless they win ten in a row next year, their campaign will have been a colossal failure.

Importantly, the Hoops are cracking on with their recruitment in the transfer market. 

Hammond is currently busy trying to bring Charlton utility man Alfie Doughty to the club.

Last week, the Bhoys had a bid rejected of around £400,000 when The Daily Record suggested Celtic wouldn't be held to ransom over the 20-year-old.

That hasn't stopped the Glaswegians from submitting an improved offer, though.

According to The Glasgow Times, they have now bid £650,000 for his services. Unfortunately, the Addicks have once again knocked that back. 

Charlton are holding out for more cash but they don't want to lose him this summer.

Doughty's contract expires at the Valley in 2021.

GIVEMESPORT'S Matt Dawson says...

Celtic have been linked with a number of full-backs this summer but out of everyone they have pursued or who is available, this one stands out as one of the best choices. 

Aaron Hickey looks like he's on his way to Bologna and if you weigh up moves for Barry Douglas and Doughty, surely a swoop for the latter makes more sense.

Douglas is now 31 and barely played any football for Leeds last season. As for Doughty, he is just 20 and has his entire career ahead of him.

Add the fact that he can play in a host of positions and he becomes an extremely attractive proposition for the Hoops.

He can play on either wing, as a central midfield or at full-back. It really is no surprise that his manager, Lee Bowyer, thinks he's "outstanding." 

However, it's on the left where he'd be needed the most.

Celtic have arguably struggled to replace Kieran Tierney since his move to Arsenal but someone like Doughty could give them hope that they have a long-term replacement. 

He provided four assists in 20 starts last season, as well as creating 0.9 key passes a match. He certainly strides forward with similar regularity to Tierney.
