Britt Assombalonga is starting to remind me of the girlfriend you let get away.

The one you allowed to leave because you thought you had a more attractive offer only to quickly regret the decision when your new partner didn't turn out to be who you thought they were.

In the summer of 2013, Britt was young, had plenty of potential and you could see a bright future together. But then your head - or to be more precise Watford owner Gino Pozzos' head - was turned by this South American beauty.

At 25, Paraguayan Javier Acuna had more experienced, had proven himself to be quite a catch (with 21 goals in 56 appearances for Girona) and was wanted by a number of your friends.

And you knew, if it didn't work out with Javier, then you had a little Italian number ready in the wings in the shape of Diego Fabbrini. An Italy international.

Troy Deeney and Fernando Forestieri had already proven their worth. There was no way you were letting them leave, so Britt was fifth in the pecking order.

Ideally, Watford would have liked to have kept the then 20-year-old in the background, just to see how it worked out with your new partners but then another man came on the scene.

Peterborough had lost one hell of a (Dwight) Gayle to Crystal Palace and wanted Britt to move in.

The club-record £1.2m offer, the 50 per cent sell-on clause and first option to buy back the striker, who was unproven at Championship level, was too good to turn down.

But Britt has blossomed. His 33 goals in 58 games for Peterborough persuaded Nottingham Forest to take him off Darren Ferguson's hands and now Watford are staring at their former love as they queue up for club Premier League.

There are only three places available and Britt's impressive form is starting to look like he may help them secure entry.

Now the decision to let Britt leave was an understandable one. He had struggled in his four Championship outings in 2012.

But the matter of whether it was the right decision is likely to be discussed in the pub with your mates for years to come. As you switch between looking into your pint and watching Britt score his eighth goal in seven league games for Forest, you are left wondering what if?

Sure his move to Nottingham landed you another £2.15m in divorce proceedings - taking the total the academy graduate earned you to more than £3.3m - but he is looking very good.

I might be wrong but taking the initial fee paid by Peterborough and the sell-on agreement into consideration, then there may have been the possibility Watford could have had him back for £2.2m plus add-ons.

That is a very expensive mistake, and one the Pozzos are unlikely to want to pay for especially as in Matej Vydra, one of the best you have ever had has returned.

There is a chance Britt could let himself go a bit and you still have plenty of talent to choose from, all vying for a bit of attention.

Hopefully come May you will be sitting on the top table in club Premier League alongside Britt reminiscing on the good old days. Not sitting in the Championship bar regretting the one you let get away.
