In many ways, Alvaro Morata's performance against Nottingham Forest said a lot about his Chelsea career. 

The Spanish international scored a brace but, with his reputation preceding him, his glaring miss from four yards in front of an open goal has proved the bigger talking point. 

Fortunately, the striker could rely on the quite brilliant Callum Hudson-Odoi, 18, who provided both assists. 

The FA Cup has taken on new importance for the holders now that they sit 10 points off the top of the Premier League table. 

The Blues have scored the fewest goals of any of the top six sides - just 38 in the league, compared to Liverpool's 49 and Manchester City's 56. 

It's little surprise then, that they are on the hunt for reinforcements in attack this month, having already signed Christian Pulisic, though the American will remain with Borussia Dortmund until the summer. 

Regarding an out-and-out striker, however, it remains to be seen whether Morata will be replaced entirely. 

There has been unconfirmed talk of a bid for PSG's Edinson Cavani, while widespread reports have also suggested that a swap deal could be on the cards for Gonzalo Higuain; Chelsea would take over his loan from Juventus to AC Milan, sending Morata to the Rossoneri. 

An apparently less ambitious, but arguably very effective move, would see the club approach Bournemouth for Callum Wilson.

Chelsea have hit a stumbling block 

Yet, according to the Mirror, it now looks unlikely that the England international will be making the move, despite the newspaper describing him as Chelsea's 'number one striker target'.

The Cherries are refusing to sanction the switch because they have already allowed Jermain Defoe to leave on loan for Rangers. 

Dominic Solanke's arrival from Liverpool - alongside Nathaniel Clyne, who comes in on loan - has filled that void and Eddie Howe does not want it to be opened again. 

What is more, Solanke is still viewed as a promising youngster who still needs to be developed, rather than a first-choice option. 

Indeed, he won't be appearing just yet anyway due to a hamstring injury. 

Wilson has scored 10 goals in 20 starts in all competitions this season and made his international debut against the USA in November. 

It might be supposed that his injury record might have deterred top clubs from taking a punt on him, but Chelsea have been watching him keenly. 

Gianfranco Zola recently admitted that Wilson was "doing well" and was "of interest not only for us but for many". 

Ironically, it looks as though Higuain may be the more realistic target.
